GL Functions

Functions that wrap OpenGL calls to accept Imath vectors and matrices.

#include <Imath/ImathGL.h>

Example:

#include <Imath/ImathGL.h>

void
gl_example()
{
    Imath::M44f M;
    glPushMatrix (M);

    Imath::V3f v (0.0f, 1.0f, 2.0f);
    glVertex (v);
}
inline void glVertex(const Imath::V2f &v)

Call glVertex2f.

inline void glVertex(const Imath::V3f &v)

Call glVertex3f.

inline void glNormal(const Imath::V3f &n)

Call glNormal3f.

inline void glColor(const Imath::V3f &c)

Call glColor3f.

inline void glTranslate(const Imath::V3f &t)

Call glTranslatef.

inline void glTexCoord(const Imath::V2f &t)

Call glTexCoord2f.

inline void throwBadMatrix(const Imath::M44f &m)

Throw an exception if m is not a valid matrix for GL.

inline void glMultMatrix(const Imath::M44f &m)

Call glMultmatrixf. Throw an exception if m is not a valid matrix for GL.

inline void glMultMatrix(const Imath::M44f *m)

Call glMultmatrixf. Throw an exception if m is not a valid matrix for GL.

inline void glLoadMatrix(const Imath::M44f &m)

Call glLoadmatrixf. Throw an exception if m is not a valid matrix for GL.

inline void glLoadMatrix(const Imath::M44f *m)

Call glLoadmatrixf. Throw an exception if m is not a valid matrix for GL.

class Imath::GLPushMatrix

A class object that pushes/pops the GL matrix.

This object assists with proper cleanup of the state when exceptions are thrown.

Public Functions

inline GLPushMatrix()
inline ~GLPushMatrix()
class Imath::GLPushAttrib

A class object that pushes/pops the current GL attribute state.

This object assists with proper cleanup of the state when exceptions are thrown.

Public Functions

inline GLPushAttrib(GLbitfield mask)

call glPushAttrib()

inline ~GLPushAttrib()

call glPopAttrib()

class Imath::GLBegin

A class object that wraps glBegin/glEnd.

The constructor calls glBegin(). The destructor calls glEnd().

Public Functions

inline GLBegin(GLenum mode)

Call glBegin()

inline ~GLBegin()

Call glEnd()
