How is texture mapping typically achieved in OpenGL? a) using geometry shader b) fragment shader c) vertex shader d) tessellation shader

Understand the Problem

The question is asking about the methods used for texture mapping in OpenGL and presents multiple choices for the answer. We need to identify the correct shader type typically used for achieving texture mapping.

More Information

The fragment shader is often used in texture mapping because it operates on a per-pixel level, allowing for detailed control over texture application and appearance.

Tips

A common mistake is assuming that texture mapping is primarily handled by the vertex shader; although it manages texture coordinates, the actual mapping and color determination are done in the fragment shader.
