Just too many issues using it. Switching to netbeans

The following issue is fixed:
• resource loader is not complete [EASY]

up till this point, all planned issues are refactored.
Planning to release 1.0 alpha by August 31. All major functionalities will present by the 1.0 alpha

one more issue fixed
• alg containers are having problems ==> fix coding style; be clear what should the data location be; implements linked list [PROPER EVALUATION]

two more issues are solving
• lacking threading and pooled memory API [INTERMEDIATE]
• too many compiler warnings ==> fix along with the above issues; change compiler flags to "treat warning as error" after to avoid future recurrence.

They will be tested in a moment.

2014-03-07 - Implemented the wireframe rasterizers and triangle clipper works correctly
So far, small test cases are not sufficient to prove the validity of the code.
• Fixing the data flow in order to load in triangle meshes from file
• Keyboard/mouse input are quite important.
But it would've been too much, I have to fix quite a lot of infrastructural facilities first. The problems I've observed so far are:
• renderer interface in the kernel doesn't sound quite integrated ==> fix this first [EASY]
• alg containers are having problems ==> fix coding style; be clear what should the data location be; implements linked list [PROPER EVALUATION]
• geometric representation does not share with other modules properly ==> thinking of moving some part of geometric control interfaces to the kernel; And create a new type of local geometric representation inside the renderer [MESSY]
• resource loader is not complete [EASY]
• lacking threading and pooled memory API [INTERMEDIATE]
• too many compiler warnings ==> fix along with the above issues; change compiler flags to "treat warning as error" after to avoid future recurrence.
These issues have to be fix as soon as possible since there are too many hacks in the current code base.... read more

Due to medical condition :(

The first prealpha will be released on 2014 Febuary 17th.

• Pre-alpha
  Rasterization Renderer [Renderer]
  A raw programmable rasterization pipeline is going to be supported. In this version(prealpha through version 1.0), shaders can be statically compiled(in c) and linked to the pipeline. GLSL dynamic shader can be written to the shader component, but they are not able to be used for the time being. Dynamic GLSL shader will not be supported by the builtin software renderer until version 1.2, while fully JITed pipeline will not appear until version 1.3. However, dynamic GLSL shader could be used by OpenGL hardware renderer as version 1.1 coming.... read more

While I am not quite familiar with Gtk OpenGL extension, I would use Cairo surface with some Gtk functions to display image for the time being. And I decide not to change the mechanism in the near future, but it should be replaced by OpenGL surface after most of the core rendering function done.

Gtk with Cairo works OK for now despite the considerable delay because of the waiting of Gtk expose event. The rendering function is now running in a separated thread from the main thread where the GUI is run. ... read more
