Function Documentation

checkOpenGLErrors()

void CSCI441::OpenGLUtils::checkOpenGLErrors ( const char *  str = "" )

inline

Checks if there are any OpenGL errors, printing them if so, and clearing the error flag.

Parameters

str	optional string to display if errors do occur (useful to help determine which call to this function triggered the errors)

debugSeverityToString()

const char * CSCI441::OpenGLUtils::debugSeverityToString ( GLenum  severity )

inline

Converts debug severity value to string representation.

Parameters

severity

debug severity

Returns

severity of debug message

debugSourceToString()

const char * CSCI441::OpenGLUtils::debugSourceToString ( GLenum  source )

inline

Converts debug source value to string representation.

Parameters

source

debug source

Returns

name of debug source

debugTypeToString()

const char * CSCI441::OpenGLUtils::debugTypeToString ( GLenum  type )

inline

Converts debug type value to string representation.

Parameters

type	debug type

Returns

type of debug message

openGLErrorMessage()

const char * CSCI441::OpenGLUtils::openGLErrorMessage ( GLenum  err )

inline

Converts error value to string representation.

Parameters

err	OpenGL error code

Returns

name of error
