<node3d>.texGen

Set the texture coordinate generation mode

<node3d>.texGen(
tg
node = ''
unit = 0
op = viz.OP_DEFAULT

)

A viz.TextureGen object. See remarks for more details.

node = ''

Name of sub-node to apply changes to

unit = 0

The texture unit to apply changes to

op = viz.OP_DEFAULT

Can be viz.OP_DEFAULT to use the nodes default op mode or a combination of the following values:

Op modes

viz.OP_TRAVERSE

When performing an operation on a node, traverse the entire subgraph and process all subnodes as well. This is the default value.

viz.OP_OVERRIDE

When applying attributes, have them override attributes of subnodes.

viz.OP_ROOT

When performing an operation on the node, start at the root transform of the node, instead of the model. Processing the root will include all child Vizard nodes.

Remarks

This command controls how automatic texture coordinates are generated when using the fixed function pipeline.

The viz.TextureGen object contains the following attributes for controlling texture coordinate generation:

viz.TEXGEN_PROJECT_MAT

matrix

Matrix transform to apply to generated coordinates.
