TexGen for embossing.

Documentation

TexGen for embossing. Shifts the texture towards the light by an amount proportional to eps. Take the difference of the filtered values generated by two emboss texgens using the same texture with +eps and -eps parameters to obtain an approximation of the diffuse dot product.

Inheritance:

TexGenEmboss - TexGen

Public Methods

TexGenEmboss (const float* tex_mat, float eps) Creates a new TexGen for embossing.

Protected Fields

float	eps Amount to shift the texture towards the light.
float	explicit_tmp_mat [16] When embossing (depends of LightParam), texcoords_explicit() needs a different matrix to transform paper position into embossed texture coordinates

Inherited from TexGen:

Public Fields

const float* explicit_mat

Protected Fields

float tex_mat[16]

float eps

Amount to shift the texture towards the light.

float explicit_tmp_mat[16]

When embossing (depends of LightParam), texcoords_explicit() needs a different matrix to transform paper position into embossed texture coordinates

TexGenEmboss(const float* tex_mat, float eps)

Creates a new TexGen for embossing.

Parameters:

- tex_mat A float vector of 12 elements, components of s, t and r vectors, respectively.
- eps mount to shift the texture towrds the light
