class RescaleNormalAttrib¶

Bases: RenderAttrib

Specifies how polygons are to be drawn.

Inheritance diagram

static make(mode: Mode) → RenderAttrib¶

Constructs a new RescaleNormalAttrib object that specifies whether to rescale normals to compensate for transform scales or incorrectly defined normals.

Return type: RenderAttrib

static makeDefault() → RenderAttrib¶

Constructs a RescaleNormalAttrib object that’s suitable for putting at the top of a scene graph. This will contain whatever attrib was suggested by the user’s rescale-normals Config variable.

Return type: RenderAttrib

getMode() → Mode¶

Returns the render mode.

Return type: Mode

static getClassSlot() → int¶

static getClassType() → TypeHandle¶

Return type: TypeHandle

property mode¶

Returns the render mode.

Return type: Mode

property class_slot¶

Return type: int

enum Mode

enumerator M_none = 0: No adjustments are made to normals.

enumerator M_rescale = 1¶: Normals are counterscaled by the transform’s uniform scale, if supported by the graphics API.

enumerator M_normalize = 2¶: Normals are scaled to unit length; potentially expensive.

enumerator M_auto = 3: Normals are counterscaled in the presence of a uniform scale transform, or normalized in the presence of a non-uniform scale transform.
