Vertex Shader - Vertex
Given a triangle object defined by 3 vertices. All it's vertices are located at the origin (0, 0, 0).
Write a vertex shader that uses the vertex index to appropriately move each vertex by 0.5 on the X and Y axes to produce a triangle on the screen.
attribute int index;
void main() {
gl_Position = vec4(0.0, 0.0, 0.0, 1.0);
}
