| void RenderScene::_validate | ( | bool | for_real | ) | [protected, virtual] |
Validate the 3D scene renderer. We construct one Scene structure per time sample. The Scene contains all primitives and lights transformed at that moment in time.

| CameraOp * RenderScene::render_camera | ( | int | sample = 0 | ) | [protected, virtual] |
Returns the camera attached to input 2(if available,) otherwise 0.

| GeoOp * RenderScene::render_geo | ( | int | sample = 0 | ) | [protected, virtual] |
Returns the GeoOp connected to input 1 for
sample.
Implements DD::Image::Render.

| Matrix4 RenderScene::camera_matrix | ( | int | sample = 0 | ) | [protected, virtual] |
Returns the inverse camera matrix for a particular sample. This supports jittering of the camera's position around the focal_point.
Reimplemented from DD::Image::Render.
References DD::Image::Render::scenes_.
| Matrix4 RenderScene::projection_matrix | ( | int | sample = 0 | ) | [protected, virtual] |
Returns the camera projection matrix for a particular sample. ARRGH! Egg makes this translate from -1..1 rather than pixels... This should be able to use CameraOp::to_format().

References DD::Image::IopInfoOwner::info_, DD::Image::Iop::sample(), and DD::Image::Render::scenes_.
| Op::HandlesMode RenderScene::doAnyHandles | ( | ViewerContext * | ctx | ) | [virtual] |
we have to shift the mode to perspective as downstream nodes will make decisions based upon that type.

| void RenderScene::build_handles | ( | ViewerContext * | ctx | ) | [virtual] |
Sets 2D viewer to 3D mode to draw any geometry in the input. Adds the camera as something that should be snapped to.

| int RenderScene::split_input | ( | int | n | ) | const [virtual] |
Return how many op inputs this operator requires for the arrow the user sees numbered n.
