GenTangentSpace()

BRK_NS_BEGIN void Geometry::GenTangentSpace ( const std::array< Vec3f, 3 > &  positions, const std::array< Vec3f, 3 > &  normals, const std::array< Vec2f, 3 > &  texCoords, std::array< Vec3f, 3 > &  tangents, std::array< Vec3f, 3 > &  bitangents  )

static

Generates tangent vectors from provided vertex data.

Note

cross(tangent,bitangent) = normal

cross(normal,tangent) = bitangent

Parameters

positions	Counterclockwise vertices positions
normals	Counterclockwise vertices positions
texCoords	Counterclockwise vertices texture coords
tangents	Output tangents vector
bitangents	Output bitangents vector
