Modify Program 2.5 so that the vertex shader includes one of the buildRotate() functions from Program 3.1 and applies it to the points comprising the triangle. This should cause the triangle to be rotated from its original orientation. You don’t need to animate the rotation.

Program 2.5

Program 3.1

Vertex Shader #version 430 void main(void) { if (gl_VertexID == 0) gl_Position = vec4( 0.25, -0.25, 0.0, 1.0); else if (gl_VertexID == 1) gl_Position vec4(-0.25, -0.25, 0.0, 1.0); else gl_Position = vec4(0.25, 0.25, 0.0, 1.0); = } Java/JOGL application - in display() gl.glDrawArrays(GL_TRIANGLES, 0, 3);
