Clean2 Project Updates [03/03/2005] James
Check out the new Projects section for updates on current research within the 60Hz group.
Clean 2.1 [28/02/2005] James
As a stepping stone to the full 3.0 release with a revised configuration and build method, multitexturing support, vertex and fragment program support and many other important features, we are rolling a few small changes into a Clean 2.1 release, due as always, "when its done".
The first of these changes was removing the dependancy on OpenIL for texture loading. Clean 2.0 now uses the more widespread libjpeg and libpng to load textures. Some heightmap loading code also made it into the current build.
New Clean2 Tutorial [15/02/2005] James
Follow the Workshops link on the left to read a short new tutorial entitled "Quickstart Guide to Rendering Your Own Data Using Clean".
Clean3 [31/01/2005] James
Discussions have begun on the new Clean version 3.0. Interested members of 60hz are encouraged to contribute to the discussion on the 60hz wiki.
Fixed Clean Rendering Libraries [01/04/2004] James
A minor update to the clean2 tarball available for download. One of the necessary header files was not included. Hopefully people will have better luck with this release. Not an April Fools joke!
New Clean Rendering Libraries tarball available for download [22/03/2004] Nick
There is a major update to the libraries page today with new versions of CL, CLU, and CLIO available for download. Documentation is also available. We plan to put up another tutorial/workshop on how to get started using the libraries, but for now I will only suggest that you have a look through the documentation and demo programs that come with the libraries. If you are entirely new to OpenGL, the previous workshops may be a good starting point. If you find the Clean Rendering Libraries useful, or if you have any problems, or if find a bug (probably one of many) please contact us.
And now to take up space, we present minimalist code snippets for loading and rendering a model using Clean (lines of code using Clean are shown in green):
CLcontext* context;
CLlight* light;
CLmodel* model;
char* filename;
static void init(void)
{
/* initialise OpenIL so that we can load textures with CLIO */
ilInit();
/* create a new context to hold the light and model */
context = clDefaultContext(clNewContext());
/* create a new light and add it to the context */
light = clDefaultLight(clNewLight());
clContextAddLight(light);
/* load a model from a file and into the context */
model = clioLoadModel(context, filename);
/* centre and scale the model to fit within the unit cube */
cluModelCentre(model);
cluModelScaleUnitCube(model);
/* updating the context generates display lists and texture objects */
clUpdateContext(context);
/* enable the depth test */
glEnable(GL_DEPTH_TEST);
/* enable lighting and the light created above */
glEnable(GL_LIGHTING);
glEnable(light->id);
/* enable texturing */
glEnable(GL_TEXTURE_2D);
}
static void display(void)
{
/* clear the colour and depth buffers */
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
/* load the light (makes all necessary OpenGL calls) */
clLoadLight(light);
glPushMatrix();
/* translate to bring model into view */
glTranslatef(0.0f, 0.0f, -5.0f);
/* render the model (makes all necessary OpenGL calls) */
clRenderModel(model);
glPopMatrix();
/* flush GL commands and swap buffers */
glFlush();
glutSwapBuffers();
}
