Web15 de mar. de 2016 · If we are going to move a texture map around by changing its texture coordinates , it is preferred that we use a “tileable” image that can be repeated over a surface. We set the texture map mode to gl.REPEAT so that texture coordinates that are transformed outside the range 0.0 to 1.0 map to a valid location in the texture image. WebTo attach a stencil buffer you use GL_STENCIL_ATTACHMENT as the second argument and specify the texture's formats as GL_STENCIL_INDEX . It is also possible to attach both a depth buffer and a stencil buffer as a single texture. Each 32 bit value of the texture then contains 24 bits of depth information and 8 bits of stencil information.

WebThe GL_REPEAT mode has textures repeat when you go past (0,0) to (1,1) range The GL_CLAMP_TO_EDGE mode has textures stop at the last pixel when you fall off the edge.
