A single rendering pass.

Documentation

A single rendering pass. The data members are public to allow modification, but when using a ready-made PaperPass, _choose one_ (and only one) of the following ways to use it:

1) using texgen - call setUp_texgen() with LightParam to use - call glVertex*() directly from the context - teardown_texgen()

2) using a vertex program - call setUp_VP with LightParam to use - call glTexCoord*() and glVertex*() directly from the context _or_ call vertex_VP() with position within the paper in array of 4 floats - call teardown_VP()

3) using explicit coordinates - call setUp_explicit with LightParam to use - call texcoords_explicit() with paper coordinates in arrays of 4 floats and call glVertex*() directly from the context. - call teardown_explicit()

Public Fields

CallGLCode	setupcode The code to call before beginning to render the pass.
CallGLCode	teardowncode The code to call after rendering the pass.
vector<shared_ptr<TexGen> >	texgen The TexGen objects for the different texture units.
vector<shared_ptr<LightSetup> >	setup The non-texgen light setup routines.

Public Methods

void	setUp_texgen (LightParam* param) Calls setupcode, texgen and setup for the texture.
void	tearDown_texgen () Calls teardowncode.
void	setUp_VP (LightParam* param) Calls setupcode, texgen and setup for the texture.
void	tearDown_VP () Calls teardowncode.
void	vertex_VP (float* pos, float* ppos) Vertex program version of the paperpass vertex.
void	setUp_explicit (LightParam* param) Calls setupcode, texgen and setup for the texture.
void	tearDown_explicit () Calls teardowncode
void	texcoords_explicit (float* ppos) Explicit version of the PaperPass texcoords

CallGLCode setupcode

The code to call before beginning to render the pass.

CallGLCode teardowncode

The code to call after rendering the pass.

vector<shared_ptr<TexGen> > texgen

The TexGen objects for the different texture units.

vector<shared_ptr<LightSetup> > setup

The non-texgen light setup routines.

void setUp_texgen(LightParam* param)

Calls setupcode, texgen and setup for the texture.

Parameters:

param - light parameters (LightParam object)

void tearDown_texgen()

Calls teardowncode.

void setUp_VP(LightParam* param)

Calls setupcode, texgen and setup for the texture.

Parameters:

param - light parameters (LightParam object)

void tearDown_VP()

Calls teardowncode.

void vertex_VP(float* pos, float* ppos)

Vertex program version of the paperpass vertex. Calling vertex_VP() is optional. It's possible to call glTexCoord*() and glVertex*() directly from the context and choose the best function variant - ie. use vertex arrays (vertex_VP() forces to pass coordinates in arrays of 4 floats).

Parameters:

pos - vertex position (array of 4 floats)
ppos - position within paper (array of 4 floats)

void setUp_explicit(LightParam* param)

Calls setupcode, texgen and setup for the texture.

Parameters:

param - light parameters (LightParam object)

void tearDown_explicit()

Calls teardowncode

void texcoords_explicit(float* ppos)

Explicit version of the PaperPass texcoords
