How can I calculate and use the normal vector of a plane to determine light reflection on surfaces in my 3D game using OpenGL?
Calculating and Using Normal Vectors for Light Reflection in OpenGL Understanding Normal Vectors Normal vectors are critical in graphics programming, especially for lighting calculations, as they define the direction perpendicular to a surface. Calculating the Normal Vector The normal vector for a plane can be calculated using the cross product […]
