Todo List

class sglBillboard

implement ePOINT_ROT_WORLD (what is the correct behaviour?).

add a setMode() to switch between Z_UP/Y_UP (or whatever). Possibly a setChildAxis function to be completely generic?

Check the computational complexity of eAXIAL_ROT and see if it can be reduced.

class sglBlending

Add support for GL_EXT_blend_color.

class sglIndexedBitMaskSwitch

Do we need to add complete mask management (remove, insert, etc)?

class sglInterleavedGeometry

Implement pick and intersect functions.

class sglLayer

Add support for intersect traversal.

Add support for the pick traversal.

class sglLight

Implement functions to set global ambient.

Implement toggle for local light model.

Implement toggle for two sided lighting.

class sglStatelet

Add sglScribe statelet (a la Performer) where wire frame is rendered on top of the filled geometry.

Add sglNormalsDisplay statelet (a la Performer) where normals are rendered along with the geometry.

class sglSwitch

Should the pick and intersect functions be implemented as wrappers to reentrant functions like cull?

class sglTransform

Add support for non-uniform scale (currently intersect traversal does not work in its presence).

class sglUnProject

Implement pick and intersect functions.
