GLTEXTUREWRAPS

GLTEXTUREWRAPS refers to OpenGL texture wrap modes, which determine how texture coordinates outside the 0 to 1 range are handled when a texture is applied to geometry. These modes control what happens when a texture coordinate is less than 0 or greater than 1. The primary wrap modes are GL_CLAMP_TO_EDGE, GL_REPEAT, and GL_MIRRORED_REPEAT. GL_CLAMP_TO_EDGE causes texels at the edge of the texture to be used for any coordinate outside the 0-1 range. This effectively stretches the edge texels. GL_REPEAT tiles the texture, meaning that coordinates less than 0 or greater than 1 will wrap around and sample from the beginning of the texture again, creating a seamless repeating pattern. GL_MIRRORED_REPEAT also tiles the texture, but it flips the texture horizontally or vertically each time it repeats. This creates a mirrored pattern effect. The specific wrap mode is set using the glTexParameter function with the GL_TEXTURE_WRAP_S and GL_TEXTURE_WRAP_T parameters for the S and T texture coordinates, respectively. Choosing the appropriate wrap mode is crucial for achieving desired visual effects, such as seamless tiling of patterns or preventing artifacts at the edges of rendered surfaces.
