Hey everyone, I'm having some trouble figuring how to properly transform my vectors to perform lighting in eye space.

Right now I'm trying to do a directional light in glsl/ opengl.

What I'm doing now:

• Transform light position by the inverse view matrix, as to transform it to eye space. This is sent as a uniform to glsl.
• In vertex shader, transform normal by mat3(view) * mat3(world). (I know i could send this as a uniform)
• The vertex in eye space is transformed by view * world and sent over the fragment shader along with the normal vector.
• In the fragment shader, the vector from eye to vertex is calculated as just (-position).

Would really appreciate some help on this.

Thanks, everything looks good now if I calculate my direction as .(lightpos - position).

However, to get a directional light it's supposed to be calculated as just normalize(lightpos). but if I change the code to be like that, the light never really shows up, no matter how i rotate the camera.

EDIT: Never mind this, I got directional lights to work by realizing i was trying to transform it as a homogenous vector when it should be a regular vector, causing it to look wrong.
