A fragment shader that textures.

Member Function Documentation

shade_triangle_pixel()

template<typename T >

Eigen::Vector4< T > eos::render::TexturingFragmentShader::shade_triangle_pixel ( int  x, int  y, const detail::Vertex< T > &  point_a, const detail::Vertex< T > &  point_b, const detail::Vertex< T > &  point_c, const Eigen::Vector3< T > &  lambda, const cpp17::optional< Texture > &  texture, float  dudx, float  dudy, float  dvdx, float  dvdy  )

inline

Todo.

See comments above about lambda (persp. corrected?).

This shader reads the colour value from the given texture. The returned colour will be in the range [0, 1]. Note/Todo: Can colour values be <0 and >1? If so, we should document and tell the user to perhaps clamp the values.

Parameters

[in]

x

X.

Returns

RGBA colour in the range [0, 1].
