Potential reworking of WebVR #3

Open Sgeo opened 7 years ago

Sgeo commented 7 years ago

The following issues may be related to the hacky approach of separate vrViewMatrix in shaders + using X3DRenderObject to drive all VR:

Background not properly shaded
Objects incorrectly not getting added to list of objects to draw
Lighting shifts with head movement in the Mall
Cobweb deciding not to draw new frames. Most observable in the Club. Cobweb needs to be informed that moving stuff exists?

Might be better to rework to have WebVR modify existing internal matrices.

Hi, yes I also came to the conclusion that it is probably necessary to update renderobject.modelviewmatrix by multiplying in vr_modelviewmatrix (or replacing it by it) since it is used in many places. It is also probably necessary to update viewpoint.cameraspacematrix and inversecameraspacematrix. https://github.com/create3000/cobweb/blob/master/cobweb.js/cobweb/Components/Layering/X3DLayerNode.js#L372 is where inversecameraspacematrix gets turned into modelviewmatrix.
