VEC3 SAMPLE PACK DOWNLOAD CODE
The complete source code of the GLSL shader is available in the PostFX_EdgeDetection.xml file. You can use the tweak bar to change the size of the different zones.
VEC3 SAMPLE PACK DOWNLOAD ARCHIVE
Unzip the demo archive somewhere, start GeeXLab and drop the file DEMO.xml in GeeXLab. This demo requires GeeXLab 0.2.10 and does not use Python so you can use the version of GeeXLab without Python (Lua only).
VEC3 SAMPLE PACK DOWNLOAD DOWNLOAD
You can download the edge detector shader (GLSL) and GeeXLab demo here: Here is an adaption for GeeXLab of the Sobel and Frei-Chen edges detectors found in this article. Frei-Chen algorithm is often used in corner detection systems.

Frei-Chen (developed in 1977) edge detector provides a slightly better edge and is less sensitive to noise. Sobel edge detector (developed in 1970) is one of the most known edge detector but is quite sensitive to noise. Sobel and Frei-Chen are two edge detection algorithms. Edge detection is a fundamental image processing technique. Left: Sobel, middle: Frei-Chen, right: regular sceneĮdge detection is a process that aims to detect sharp changes in the color intensity of an image. Bugfix: crash in HYP_Mesh.DoTweening() when meshes have not the same number of vertices (Lua only).Bugfix: outline fonts did not work with shadow mapping.Bugfix: in Check_AABB_Collision() and Check_BS_Collision() of HYP_Object lib (Lua).New: added gpu_shader_z_pass and gpu_program_z_pass attributes to particle_system node (xml).New: added active attribute to shadow_mapping element of scene node (xml).New: added shader_program_name_z_pass attribute to material node (xml).New: added SetGpuProgramZPass() and SetShaderProgramZPass() to HYP_Material lib (Python / Lua).For an overview of GeeXLab, just read this article. All rendering is done with the OpenGL API. GeeXLab language uses a simple mixture of XML, Lua and/or Python and GLSL.

You code your 3D scene in one or several source code files, you load the main scene file in GeeXLab and GeeXLab displays the scene. GeeXLab can be seen as a real time 3D scene browser (like Firefox for html scripts). GeeXLab is a tool (we can call it a demotool) for quick coding and prototyping of real time 3D scenes. GeeXLab support forums are available HERE (french) and HERE (english).įor Twitter addicts, you can follow GeeXLab tweets here: – What is GeeXLab? You can also download GeeXLab 0.2.10 from FilePlanet.Īll GeeXLab news including tutorials and demos: GeeXLab News. The version of GeeXLab with Python support requires the Python 2.6.6 32-bit installer (or Python 2.7 32-bit installer or Python 3.2 32-bit) even on 64-bit OSes. Two versions are packed in the installer: GeeXLab_Lua and GeeXLab_Python_Lua. Left-click to download (right-click disabled) Discover Australia Interactive Floor is an example of application developed by Lumen with GeeXLab (actually Discover Australia has been developed with Hyperion, the ancestor of GeeXLab, back to 2007!): The guys at Lumen know their work so if you’re looking for some good Lua code samples, check out their demos. The mesh bouncer and sound spectrum visualizer demos are a contribution of Lumen Digital. Sound spectrum visualizer demo (Lua_Sound_Spectrum_Viz/ folder) The code samples pack has been updated with new demos:Īnimated caustic demo (Lua_Caustic_Anim/ folder) More details in the changelog at the end of the post. GeeXLab 0.2.10 adds few new things related to shadow mapping and brings some bugfixes. Shadow mapping demo (Shadow_Mapping/ folder)Ī new version of GeeXLab is ready. More information and download: The SuperShaper. A little bug that will be quickly fixed in the next iteration of SuperShaper I think! Only NVIDIA OpenCL plateform is installed, and maybe this is the source of the error. But on my dev station with an ASUS Radeon HD 6950 (primary card) + GeForce GT 240 (second card, OpenCL 1.0 is ok according to GPU Caps Viewer) I got the following error message: On my testbed with an single graphics card (a GTX 5×0…), SuperShaper has worked fine. I loaded the exported mesh in a simple GeeXLab scene: SuperShaper can export the 3D shape to 3ds Max mesh format (*.3ds).

Shader based rendering with reflection and different per pixel lighting models.Toroidal or Spherical volumetric transformation.Create endless amounts of different 3D shapes.OpenCL 1.0 is used to implement the superformula while OpenGL 3.2 has been chosen for the 3D rendering. SuperShaper is a tool based on the superformula (a mathematical formula, dicovered by Johan Gielis, to describe many shapes existing in nature) to create detailed 3D shapes.
