Beta revisions of the OpenGL screen savers Solar Winds (particle effects) and Skyrocket (fireworks with OpenAL sound) have been posted. There is some new functionality that should be thoroughly tested by real-world use before any of it is finalized. Bug reports and comments are welcomed.
VRMesh 2.0 is a sketch-based free-form OpenGL API-based 3D modeling software for arbitrary triangle mesh creating and processing. The new version adds many new features including fixing mesh tools, project fi9llet, clip painted reation for arbitrary trimming, profile-based editing as well as enhanced smoothing, Boolean and knife editing. It also adds a new interface.
FreeStyler is a simplified CAD design tool for quick and easy sketching. This first release supports linear, surface, surface opening and dimension elements and uses a tree explorer and property window. The rendering uses the OpenGL API and the interface uses MFC.
This module is intended to help 3D-naive students learn how to model in 3D. Content can be place online, for marking by lecturers remotely, peer-review by friends, or for potential employers to view. The OpenGL API is used extensively in both the PC and Mac versions, and supports advanced features such as particle effects, and reflection mapping.
The OpenGL Extension Wrangler Library (GLEW) is a cross-platform C/C++ extension loading library. The latest release includes support for the EXT_framebuffer_object and ARB_pixel_buffer_object extensions in addition to fixing the bugs in the previous release.
GLUT, the OpenGL Utility Toolkit, is a window system independent toolkit for writing OpenGL programs. GLUT | ES is a port of the OpenSource FreeGLUT implementation for WinCE and Win32 systems based on OpenGL ES. Most of GLUT API v.3 functionnalities are present: window creation, callbacks, menus, timers etc. Only functions that cannot exist with OpenGL ES or are not pertinent have not been ported (like overlays, joysticks on PocketPC, etc.)
SGPV (Scene Graph Property Viewer) is a new framework to edit the OpenGL API-based Gizmo3D Scene Graph. It is a GUI billboard application that allows components to register GUIs, Menues, Popups, Bitmaps etc. so they can be displayed in a stand alone framework. The SGPV app uses the CCT (Contents Creation Toolkit) components to display scene graph properties like hierarchy, states, shaders, textures, material etc. The CCT components can also be used within 3D Studio, Maya and even in your own stand alone Gizmo3D application to edit your scene and debug traversals, states, texture load, optimizations etc.
Quesa is a high-level 3D graphics library built on top of the OpenGL API that supports retained and immediate mode rendering, an extensible file format, plug-in renderers, a wide range of high level geometries, hierarchical models, and a consistent and object-orientated API. The new v1.6d20 improves rendering transparency, adds a 32-bit depth buffer from OpenGL, and shares texture memory between draw contexts.
The OpenGL ES Coding Challenge is entering the final phase with submissions due by Feb 15, 2005. The Challenge is open to coders on handhelds, as well as desktop Win32 and Linux. Prizes include travel, PDAs, cell phones, accelerators boards, coding books, training classes and more.
This Master’s Thesis presents how to implement a ray tracer supporting reflection, refraction, texturing and more, using C++, GLUT, the OpenGL API and pixel shaders & vertex shaders. It also present a way to speed up rendering (relative to standard grid traversal) using proximity clouds. Source code and the full thesis is available for download.
iDance with D-Player is a real time OpenGL API-based 3D dance learning environment where a cyberdancer dances to music. The user can see the latest dance moves by selecting the characters and watching them in slow motion, section repetition, angle-adjusting function, zoom in and zoom out. Since the dance data is motion captured data from actual professional dancers, the movements are fluid and natural.
gDEBugger is an OpenGL API debugger, traces application activity on top of the OpenGL API letting programmers see what is happening within the graphic system implementation. The new v1.2 includes an interactive texture viewer that displays render contexts texture objects, texture objects parameters and the textures’ data as an image. 1D, 2D, 3D and cube map texture data viewing is supported. This version also includes performance improvements, bug fixes and new OpenGL extensions support.
These two texturing tutorials explain how to generating textures and use BMP files to texture objects for OpenGL API rendering. The site also features other game related tutorials including a port of the texturing tutorial to SDL for non-Windows OSes.
AgentFX is a platform independent 3D-engine written in Java and uses the OpenGL API to deliver high-end features like real-time shadow volumes and dynamic lights. The new v2.1.1 of AgentFX is mainly an update but also integerates skelton-based models with shaders using Cg language. Tutorials shows how to use shader-skinned skelton-based models.
The latest v0.95 release of LWJGL includes support for the recently recently released EXT_framebuffer_object extension. LWJGL provides Java developers access to high performance cross-platform libraries such as the OpenGL and OpenAL APIs allowing for state of the art 3D games and 3D sound.
