Detailed Description

SoColTabMultiTexture2 combines one or more textures of the same size into one. All textures are put in a sequence in SoColTabMultiTexture2::image, and the sequence is processed from the start to the end to create one texture.

Member Enumeration Documentation

enum SoColTabMultiTexture2::Component

Specifies which components that are affected by the current texture.

Enumerator:

RED
GREEN
BLUE
OPACITY

enum SoColTabMultiTexture2::Operator

Specifies how a texture should interact with the previous texture(s).

Enumerator:

BLEND	The current texture is mixed with the previous texture(s) depending on the value of the opacity component.
ADD	The average between the previous texture(s) and the current texture is taken.
REPLACE	The old texture(s) is replaced by the current one.
