RemarksCube map textures provide a new texture generation scheme for looking up textures from a set of six two-dimensional images representing the faces of a cube. The (s,t,r) texture coordinates are treated as a direction vector emanating from the center of a cube. At texture generation time, the interpolated per-fragment (s,t,r) selects one cube face two-dimensional image based on the largest magnitude coordinate (the major axis). A new (s,t) is calculated by dividing the two other coordinates (the minor axes values) by the major axis value, and the new (s,t) is used to lookup into the selected two-dimensional texture image face of the cube map.
Cube map textures are often used within shader programs to implement effects such as reflection or refraction.
There are three ways to send the texture to Open Inventor:
The textures can be read from six image files specified in the OIV.Inventor.Nodes.SoTextureCubeMap.filenames field.
Textures can be specified in memory by setting the image fields (OIV.Inventor.Nodes.SoTextureCubeMap.imagePosX, ...) to contain the texture data. Doing so resets the OIV.Inventor.Nodes.SoTextureCubeMap.filenames field to the empty string.
Textures can be rendered from a scene graph using the renderToTextureProperty field.
But in all cases, the images must be specified in the following order:
imagePosX (left)
imagePosY (bottom)
imagePosZ (back)
imageNegX (right)
imageNegY (top)
imageNegZ (front)
The OIV.Inventor.Nodes.SoTextureCoordinateReflectionMap node can be used to automatically generate appropriate texture coordinates for cube mapping.
If the texture image's width or height is not a power of 2, and the Non Power Of Two (NPOT) extension is available on your graphics board, by default Open Inventor will send the image to OpenGL without modification. See OIV.Inventor.Nodes.SoTexture2 for a complete discussion of this feature.
Transparency Texture images can contain transparency (alpha values less than 1) and modify the transparency of geometry in the scene. Also note that some image file formats, for example JPEG, do not support transparency information (alpha channel).
Limitations:
Since Open Inventor 10.0.0 Alpha 2 it is no longer possible to fill a OIV.Inventor.Nodes.SoTextureCubeMap with textures in different formats or sizes. All six textures must have the same format and size. If these conditions are not met, an error message is displayed (in debug) and nothing is changed on the state.
EXAMPLE
SoInput.AddDirectoryFirst("/ImageDirectory"); string[] faceFile = { "left.jpg", "bottom.jpg", "back.jpg", "right.jpg", "top.jpg", "front.jpg", }; SoTextureCubeMap texture = new SoTextureCubeMap(); for (int i = 0; i < 6; ++i) { texture.filenames[i] = faceFile[i]; } root.AddChild( new SoTextureCoordinateReflectionMap() ); root.AddChild( texture ); root.AddChild( geometry );
