6. Compiling a shader program

1. Compile a vertex shader -> returns shader ID

2. Compile a fragment shader -> returns shader ID

3. Check for compilation errors

4. Create a shader program -> returns program ID

   • Retain this program ID in your code

5. Attach to a vertex and fragemnt shaders to the program

6. Link those two shaders together

7. Use program ID before you render triangles

   • Separate shaders may be used for different objects (see next slide)
