Detailed Description

Class for creating a texture by rendering a scene graph

This class is used to define an image for texture mapping which is created by rendering a scene graph.

It can be used with the classes SoTexture2 and SoTextureCubeMap. Create the SoRenderToTextureProperty node and assign it to the renderToTextureProperty field of the texture mapping node.

The SoRenderToTarget node can also be used to create texture images.

One of the two fields, node or path, must be defined.

The scene graph should normally contain a camera and at least one light. Unlike SoRenderToTarget, the children of SoRenderToTextureProperty do not inherit the camera, lights, etc from the main scene graph.

Note that the default image size is 0,0 (effectively disables rendering).

Member Enumeration Documentation

◆ Component

enum SoRenderToTextureProperty::Component

Rendering component enumeration values.

Enumerator
RGB	Default. The RGB components are rendered to the texture.
RGB_TRANSPARENCY	The RGB and alpha components are rendered to the texture.
RGB_ALPHA
DEPTH	The depth component is rendered to the texture.

Definition at line 131 of file SoRenderToTextureProperty.h.

◆ UpdatePolicy

enum SoRenderToTextureProperty::UpdatePolicy

Update Policy enumeration values.

Enumerator

EACH_FRAME

The texture is updated at each traversal of the shape it is mapped to.

WHEN_NEEDED

Default.

The texture is updated only if the path or node fields have changed.

ON_TRIGGER

The texture is updated only if the trigger field is touched.

Definition at line 114 of file SoRenderToTextureProperty.h.

Member Data Documentation

◆ backgroundColor

SoSFColor SoRenderToTextureProperty::backgroundColor

Background color used when rendering the scene graph.

Black by default.

◆ node

SoMFNode SoRenderToTextureProperty::node

Specifies the scene graph(s) (SoNode(s)) to be rendered into the texture.

For use with SoTexture2, only one scene graph should be specified. For use with SoTextureCube map, six scene graphs must be specified, one for each face of the cube in the order:

imagePosX (left)
imageNegX (right)
imagePosY (bottom)
imageNegY (top)
imagePosZ (back)
imageNegZ (front)

The node field has priority over the path field. Null by default.

Definition at line 165 of file SoRenderToTextureProperty.h.

◆ path

SoMFPath SoRenderToTextureProperty::path

Specifies the scene graph(s) (SoPath(s)) to be rendered into the texture.

For use with SoTexture2, only one path should be specified. For use with SoTextureCube map, six paths must be specified, one for each face of the cube in the order:

imagePosX (left)
imageNegX (right)
imagePosY (bottom)
imageNegY (top)
imagePosZ (back)
imageNegZ (front)

The node field has priority over the path field. Null by default.

Definition at line 182 of file SoRenderToTextureProperty.h.

◆ size

SoSFVec2s SoRenderToTextureProperty::size

Size in pixels of the rendered texture.

(0, 0) by default.

Definition at line 199 of file SoRenderToTextureProperty.h.

◆ trigger

SoSFTrigger SoRenderToTextureProperty::trigger

Trigger field to render the scene into the Pbuffer.

Effective only if updatePolicy is ON_TRIGGER.

Definition at line 211 of file SoRenderToTextureProperty.h.

◆ updatePolicy

SoSFEnum SoRenderToTextureProperty::updatePolicy

Specifies the policy for rendering to the texture.

Use enum UpdatePolicy. Default is WHEN_NEEDED.
