getComponentMat3 LMatrix3d const &EggTransform::get_component_mat3(int n) const; Description: Returns the 3x3 matrix associated with the nth component. It is an error to call this if the component type is not CT_matrix3. |
getComponentMat4 LMatrix4d const &EggTransform::get_component_mat4(int n) const; Description: Returns the 4x4 matrix associated with the nth component. It is an error to call this if the component type is not CT_matrix4. |
getComponentNumber double EggTransform::get_component_number(int n) const; Description: Returns the solitary number associated with the nth component. In the case of a rotation, this is the angle in degrees to rotate; in the case of uniform scale, this is the amount of the scale. Other types do not use this property. |
getComponentType EggTransform::ComponentType EggTransform::get_component_type(int n) const; Description: Returns the type of the nth component. |
getComponentVec2 LVecBase2d const &EggTransform::get_component_vec2(int n) const; Description: Returns the 2-component vector associated with the nth component. This may be the translate vector, rotate axis, or non-uniform scale. It is an error to call this if the component type does not use a 2-d vector property. |
getComponentVec3 LVecBase3d const &EggTransform::get_component_vec3(int n) const; Description: Returns the 3-component vector associated with the nth component. This may be the translate vector, rotate axis, or non-uniform scale. It is an error to call this if the component type does not use a 3-d vector property. |
getNumComponents int EggTransform::get_num_components(void) const; Description: Returns the number of components that make up the transform. |
getTransform2d LMatrix3d EggTransform::get_transform2d(void) const; Description: Returns the overall transform as a 3x3 matrix. It is an error to call this if has_transform3d() is true. |
getTransform3d LMatrix4d const &EggTransform::get_transform3d(void) const; Description: Returns the overall transform as a 4x4 matrix. It is valid to call this even if has_transform2d() is true; in this case, the 3x3 transform will be expanded to a 4x4 matrix. |
hasTransform bool EggTransform::has_transform(void) const; Description: Returns true if the transform is nonempty, false if it is empty (no transform components have been added). This is true for either a 2-d or a 3-d transform. |
hasTransform2d bool EggTransform::has_transform2d(void) const; Description: Returns true if the transform is specified as a 2-d transform, e.g. with a 3x3 matrix, or false if it is specified as a 3-d transform (with a 4x4 matrix), or not specified at all. Normally, EggTextures have a 2-d matrix (but occasionally they use a 3-d matrix), and EggGroups always have a 3-d matrix. |
hasTransform3d bool EggTransform::has_transform3d(void) const; Description: Returns true if the transform is specified as a 3-d transform, e.g. with a 4x4 matrix, or false if it is specified as a 2-d transform (with a 2x2 matrix), or not specified at all. Normally, EggTextures have a 3-d matrix (but occasionally they use a 3-d matrix), and EggGroups always have a 3-d matrix. |
