The ID3DXRenderToEnvMap interface is used to generalize the process of rendering to environment maps.
| Method | Description |
|---|---|
| ID3DXRenderToEnvMap::BeginCube | Initiate the rendering of a cubic environment map. |
| ID3DXRenderToEnvMap::BeginHemisphere | Initiate the rendering of a hemispheric environment map. |
| ID3DXRenderToEnvMap::BeginParabolic | Initiate the rendering of a parabolic environment map. |
| ID3DXRenderToEnvMap::BeginSphere | Initiate the rendering of a spherical environment map. |
| ID3DXRenderToEnvMap::End | Restore all render targets and, if needed, compose all the rendered faces into the environment map surface. |
| ID3DXRenderToEnvMap::Face | Initiate the drawing of each face of an environment map. |
| ID3DXRenderToEnvMap::GetDesc | Retrieves the description of the render surface. |
| ID3DXRenderToEnvMap::GetDevice | Retrieves the Direct3D device associated with the environment map. |
| ID3DXRenderToEnvMap::OnLostDevice | Use this method to release all references to video memory resources and delete all stateblocks. This method should be called whenever a device is lost, or before resetting a device. |
| ID3DXRenderToEnvMap::OnResetDevice | Use this method to re-acquire resources and save initial state. |
An environment map is used to texture-map scene geometry to provide a more sophisticated scene without using complex geometry. This interface supports creating surfaces for the following kinds of geometry: cube, half sphere or hemispheric, parabolic, or sphere.
The ID3DXRenderToEnvMap interface is obtained by calling the D3DXCreateRenderToEnvMap function.
The LPD3DXRenderToEnvMap type is defined as a pointer to the ID3DXRenderToEnvMap interface.
