Texture streaming is a means of using data streams for textures, where each texture is available in two or more different resolutions, as to determine which texture should be loaded into memory and used based on draw distance from the viewer and how much memory is available for textures. Texture streaming allows for rendering engine to use low resolution textures for objects far away from the viewer's camera, and resolve those into more detailed textures, read from a data source, as the point of view nears the objects.

As an optimization, it is possible to render detail from a complex, high-resolution model or expensive process (such as global illumination) into a surface texture (possibly on a low-resolution model). Baking is also known as render mapping. This technique is most commonly used for light maps, but may also be used to generate normal maps and displacement maps. Some computer games (e.g. Messiah) have used this technique. The original Quake software engine used on-the-fly baking to combine light maps and colour maps ("surface caching").

Baking can be used as a form of level of detail generation, where a complex scene with many different elements and materials may be approximated by a single element with a single texture, which is then algorithmically reduced for lower rendering cost and fewer drawcalls. It is also used to take high-detail models from 3D sculpting software and point cloud scanning and approximate them with meshes more suitable for realtime rendering.

Various techniques have evolved in software and hardware implementations. Each offers different trade-offs in precision, versatility and performance.

Best Texture Packs

Some hardware systems e.g. Sega Saturn and the NV1 traverse texture coordinates directly, interpolating the projected position in screen space through texture space and splatting the texels into a frame buffer. (in the case of the NV1, quadratic interpolation was used allowing curved rendering). Sega provided tools for baking suitable per-quad texture tiles from UV mapped models.

This has the advantage that texture maps are read in a simple linear fashion.

Forward texture mapping may also sometimes produce more natural looking results than affine texture mapping if the primitives are aligned with prominent texture directions (e.g. road markings or layers of bricks). This provides a limited form of perspective correction. However, perspective distortion is still visible for primitives near the camera (e.g. the Saturn port of Sega Rally exhibited texture-squashing artifacts as nearby polygons were near clipped without UV coordinates).

This technique is not used in modern hardware because UV coordinates have proved more versatile for modelling and more consistent for clipping.

Best Shader Mods

Most approaches use inverse texture mapping, which traverses the rendering primitives in screen space whilst interpolating texture coordinates for sampling. This interpolation may be affine or perspective correct. One advantage is that each output pixel is guaranteed to only be traversed once; generally the source texture map data is stored in some lower bit-depth or compressed form whilst the frame buffer uses a higher bit-depth. Another is greater versatility for UV mapping. A texture cache becomes important for buffering reads, since the memory access pattern in texture space is more complex.

Because affine texture mapping does not take into account the depth information about a polygon's vertices, where the polygon is not perpendicular to the viewer, it produces a noticeable defect.

Affine texture mapping linearly interpolates texture coordinates across a surface, and so is the fastest form of texture mapping. Some software and hardware (such as the original PlayStation) project vertices in 3D space onto the screen during rendering and linearly interpolate the texture coordinates in screen space between them ("inverse texture mapping"[citation needed]). This may be done by incrementing fixed pointUV coordinates, or by an incremental error algorithm akin to Bresenham's line algorithm.

In contrast to perpendicular polygons, this leads to noticeable distortion with perspective transformations (see figure: the checker box texture appears bent), especially as primitives near the camera. Such distortion may be reduced with the subdivision of the polygon into smaller ones.

Doom engine renders vertical and horizontal spans with affine texture mapping, and is therefore unable to draw ramped floors or slanted walls.

Essential Minecraft Mods

Perspective correct texturing accounts for the vertices' positions in 3D space, rather than simply interpolating coordinates in 2D screen space.[11] This achieves the correct visual effect but it is more expensive to calculate.[11]

To perform perspective correction of the texture coordinates u{\displaystyle u} and v{\displaystyle v}, with z{\displaystyle z} being the depth component from the viewer's point of view, we can take advantage of the fact that the values 1z{\displaystyle {\frac {1}{z}}}, uz{\displaystyle {\frac {u}{z}}}, and vz{\displaystyle {\frac {v}{z}}} are linear in screen space across the surface being textured. In contrast, the original z{\displaystyle z}, u{\displaystyle u} and v{\displaystyle v}, before the division, are not linear across the surface in screen space. We can therefore linearly interpolate these reciprocals across the surface, computing corrected values at each pixel, to result in a perspective correct texture mapping.

To do this, we first calculate the reciprocals at each vertex of our geometry (3 points for a triangle). For vertex n{\displaystyle n} we have unzn,vnzn,1zn{\displaystyle {\frac {u_{n}}{z_{n}}},{\frac {v_{n}}{z_{n}}},{\frac {1}{z_{n}}}}. Then, we linearly interpolate these reciprocals between the n{\displaystyle n} vertices (e.g., using Barycentric Coordinates), resulting in interpolated values across the surface. At a given point, this yields the interpolated ui,vi{\displaystyle u_{i},v_{i}}, and zReciprocali=1zi{\displaystyle zReciprocal_{i}={\frac {1}{z_{i}}}}. Note that this ui,vi{\displaystyle u_{i},v_{i}} cannot be yet used as our texture coordinates as our division by z{\displaystyle z} altered their coordinate system.

To correct back to the u,v{\displaystyle u,v} space we first calculate the corrected z{\displaystyle z} by again taking the reciprocal zcorrect=1zReciprocali=11zi{\displaystyle z_{correct}={\frac {1}{zReciprocal_{i}}}={\frac {1}{\frac {1}{z_{i}}}}}. Then we use this to correct our ui,vi{\displaystyle u_{i},v_{i}}: ucorrect=uizi{\displaystyle u_{correct}=u_{i}\cdot z_{i}} and vcorrect=vizi{\displaystyle v_{correct}=v_{i}\cdot z_{i}}.[12]

This correction makes it so that in parts of the polygon that are closer to the viewer the difference from pixel to pixel between texture coordinates is smaller (stretching the texture wider) and in parts that are farther away this difference is larger (compressing the texture).

Affine texture mapping directly interpolates a texture coordinate uα{\displaystyle u_{\alpha }^{}} between two endpoints u0{\displaystyle u_{0}^{}} and u1{\displaystyle u_{1}^{}}:
uα=(1α)u0+αu1{\displaystyle u_{\alpha }^{}=(1-\alpha )u_{0}+\alpha u_{1}} where 0α1{\displaystyle 0\leq \alpha \leq 1}
Perspective correct mapping interpolates after dividing by depth z{\displaystyle z_{}^{}}, then uses its interpolated reciprocal to recover the correct coordinate:
uα=(1α)u0z0+αu1z1(1α)1z0+α1z1{\displaystyle u_{\alpha }^{}={\frac {(1-\alpha ){\frac {u_{0}}{z_{0}}}+\alpha {\frac {u_{1}}{z_{1}}}}{(1-\alpha ){\frac {1}{z_{0}}}+\alpha {\frac {1}{z_{1}}}}}}

3D graphics hardware typically supports perspective correct texturing.

Various techniques have evolved for rendering texture mapped geometry into images with different quality/precision tradeoffs, which can be applied to both software and hardware.

Classic software texture mappers generally did only simple mapping with at most one lighting effect (typically applied through a lookup table), and the perspective correctness was about 16 times more expensive.

Restricted camera rotation[edit]

The Doom engine restricted the world to vertical walls and horizontal floors/ceilings, with a camera that could only rotate about the vertical axis. This meant the walls would be a constant depth coordinate along a vertical line and the floors/ceilings would have a constant depth along a horizontal line. A fast affine mapping could be used along those lines because it would be correct. Some later renderers of this era simulated a small amount of camera pitch with shearing which allowed the appearance of greater freedom whilst using the same rendering technique.

Some engines were able to render texture mapped Heightmaps (e.g. Nova Logic's Voxel Space, and the engine for Outcast) via Bresenham-like incremental algorithms, producing the appearance of a texture mapped landscape without the use of traditional geometric primitives.[13]

Subdivision for perspective correction[edit]

Every triangle can be further subdivided into groups of about 16 pixels in order to achieve two goals. First, keeping the arithmetic mill busy at all times. Second, producing faster arithmetic results.[vague]

4. Open Resource Pack Folder & Paste .Zip File

For perspective texture mapping without hardware support, a triangle is broken down into smaller triangles for rendering and affine mapping is used on them. The reason this technique works is that the distortion of affine mapping becomes much less noticeable on smaller polygons. The Sony PlayStation made extensive use of this because it only supported affine mapping in hardware but had a relatively high triangle throughput compared to its peers.

3. From Main Menu > Options > Resource Packs

Software renderers generally preferred screen subdivision because it has less overhead. Additionally, they try to do linear interpolation along a line of pixels to simplify the set-up (compared to 2d affine interpolation) and thus again the overhead (also affine texture-mapping does not fit into the low number of registers of the x86 CPU; the 68000 or any RISC is much more suited).

A different approach was taken for Quake, which would calculate perspective correct coordinates only once every 16 pixels of a scanline and linearly interpolate between them, effectively running at the speed of linear interpolation because the perspective correct calculation runs in parallel on the co-processor.[14] The polygons are rendered independently, hence it may be possible to switch between spans and columns or diagonal directions depending on the orientation of the polygon normal to achieve a more constant z but the effort seems not to be worth it.

5. Check "Resource Packs" In Game To Find Texture Pack

Another technique was approximating the perspective with a faster calculation, such as a polynomial. Still another technique uses 1/z value of the last two drawn pixels to linearly extrapolate the next value. The division is then done starting from those values so that only a small remainder has to be divided[15] but the amount of bookkeeping makes this method too slow on most systems.

Finally, the Build engine extended the constant distance trick used for Doom by finding the line of constant distance for arbitrary polygons and rendering along it.

Hardware implementations[edit]

Texture mapping hardware was originally developed for simulation (e.g. as implemented in the Evans and Sutherland ESIG image generators), and professional graphics workstations such as Silicon Graphics, broadcast digital video effects machines such as the Ampex ADO and later appeared in Arcade cabinets, consumer video game consoles, and PC video cards in the mid 1990s. In flight simulation, texture mapping provided important motion cues.

Modern graphics processing units (GPUs) provide specialised fixed function units called texture samplers, or texture mapping units, to perform texture mapping, usually with trilinear filtering or better multi-tap anisotropic filtering and hardware for decoding specific formats such as DXTn. As of 2016, texture mapping hardware is ubiquitous as most SOCs contain a suitable GPU.

Some hardware combines texture mapping with hidden-surface determination in tile based deferred rendering or scanline rendering; such systems only fetch the visible texels at the expense of using greater workspace for transformed vertices. Most systems have settled on the Z-buffering approach, which can still reduce the texture mapping workload with front-to-back sorting.


Beyond 3D rendering, the availability of texture mapping hardware has inspired its use for accelerating other tasks:


It is possible to use texture mapping hardware to accelerate both the reconstruction of voxel data sets from tomographic scans, and to visualize the results[16]

User interfaces[edit]

Many user interfaces use texture mapping to accelerate animated transitions of screen elements, e.g. Exposé in Mac OS X.
