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. The GL_CLAMP and GL_CLAMP_TO_BORDER are depreciated because all texture borders must be 0 pixels, so the modes don't make sense anymore. (somewhere around … 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.
