Frames per second printing + + GLUT now looks for an environment variable called "GLUT_FPS". If it's + set, GLUT will print out a frames/second statistic to stderr when + glutSwapBuffers() is called. By default, frames/second is computed + and displayed once every 5 seconds. You can specify a different + interval (in milliseconds) when you set the env var. For example + 'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval + to one second. + + NOTE: the demo or application must call the glutInit() function for + this to work. Otherwise, the env var will be ignored. + + Finally, this feature may not be reliable in multi-window programs. + + +2. glutGetProcAddress() function + + The new function: + + void *glutGetProcAddress(const char *procName) + + is a wrapper for glXGetProcAddressARB() and wglGetProcAddress(). It + lets you dynamically get the address of an OpenGL function at runtime. + The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the + GLUT version number from 3.7 since that's probably Mark Kilgard's role. + + This function should probably also be able to return the address of + GLUT functions themselves, but it doesn't do that yet. + + + XXX Things To Do Yet XXXX ------------------------- @@ -215,4 +250,4 @@ are some things to change: ---------------------------------------------------------------------- -$Id: RELNOTES-4.1,v 1.14 2002/08/01 15:16:46 brianp Exp $ +$Id: RELNOTES-4.1,v 1.15 2002/08/17 00:23:19 brianp Exp $ |
