Lighting model leaves some areas of 3d models quite dark #42

Closed jamievicary closed 5 years ago

The lighting on the 3d models is really nice; they have a beautiful and rich matt texture, with specular reflections that change as the model rotates, and bright colours when seen from the 'front', like this:

pentagonator_front_side

However, unlike the 'front' side, the 'reverse' side of the model is quite dark and flat, which makes it less visually appealing from some angles, and makes it harder to perceive details:

pentagonator_reverse_side

It would be good to brighten this up somewhat. It would be nice if the whole model had uniform texture and surface qualities, with the richness of variations of colour intensity and tone --- which are important both for visual appeal, and to allow the 3d geometry to be more easily understood --- coming by interaction with the light source as the model is rotated.

By the way, this is a surface model of the pentagon equation.

Solved by adding more lights to the scene, and attaching the lights to the camera so that they appear fixed when rotating the model.
