One is to store the UVs for all 3 axis on the mesh itself. including sprite batching, texture atlases, parallax scrolling. Texture Atlas Whitepaper - A whitepaper by NVIDIA which explains the technique. There’s three ways to go about doing triplanar mapping with an atlas.Mozilla Development Network.Įxternal links Explanations and algorithms ^ "Implementing image sprites in CSS".
^ a b "SDK White Paper Improve Batching Using Texture Atlases" (PDF).In web development, images are packed into a sprite sheet to reduce the number of image resources that need to be fetched in order to display a page. Careful alignment may be needed to avoid bleeding between sub textures when used with mipmapping and texture compression. This reduces both the disk I/O overhead and the overhead of a context switch by increasing memory locality.
In an application where many small textures are used frequently, it is often more efficient to store the textures in a texture atlas which is treated as a single unit by the graphics hardware. 1628, The Physics Editor Exporter (found in the resources folder of the repo). A sub-image is drawn using custom texture coordinates to pick it out of the atlas. 1112, WebGL and Canvas both now support rotated texture atlas frames. An atlas can consist of uniformly-sized images or images of varying dimensions. In computer graphics, a texture atlas (also called a spritesheet or an image sprite in 2d game development) is an image containing multiple smaller images, usually packed together to reduce overall dimensions. Large image containing an atlas of sub-images
