void mrpt::opengl::gl_utils::TRenderInfo::projectPoint ( float  x,
float  y,
float  z,
float &  proj_x,
float &  proj_y,
float &  proj_z_depth 
) const
inline

Computes the normalized coordinates (range=[0,1]) on the current rendering viewport of a point with local coordinates (wrt to the current model matrix) of (x,y,z).

The output proj_z_depth is the real distance from the eye to the point.

float  y,
float  z,
float &  proj_x_px,
float &  proj_y_px,
float &  proj_z_depth 
) const
inline

Exactly like projectPoint but the (x,y) projected coordinates are given in pixels instead of normalized coordinates.
