The Mediocre Media Player is a simple media player for Win32, designed to be small, fast and flexible. It uses OpenGL for rendering and developers may be interested in the source code as it implements video textures using the OpenGL Shading Language that are actually faster than DirectShow overlay rendering on ATI cards.
MachineWorks V6.1 CNC simulation/verification application adds OpenGL API-based metallic effect rend
The new MachineWorks v6.1 adds OpenGL API-based rendering of realistic metallic effect within its animations. It also adds analytical functions to improve the detection of collisions, gouges and undercuts within the different MachineWorks engines and OpenGL API rendering with wire-frame, hidden line removal, colour shading, transparency ,texture mapping and shadows.
The NVIDIA Scene Graph Software Development Kit (NVSG SDK) is an object-oriented programming library (C++) for creating scenegraph-based applications. The NVSG SDK provides a comprehensive set of classes that developers can easily combine and extend to create fast and reliable graphics applications. It is optimized for Nvidia Quadro hardware and operates on top of the OpenGL API in either 32-or 64-bit Windows or Linux.
Nvidia Cg 1.3 beta 2 supports OpenGL fixed-function state vectors from within ARB_vertex_program and
Nvidia Cg 1.3 beta 2 add new features including semantics to access OpenGL fixed-function state vectors from within ARB_vertex_program and ARB_fragment_program, vp40 profile to enables texture sampling from within vertex programs, new fp40 profile, which provides a robust branching model in fragment programs, and support for output to multiple draw buffers, and a fast precision option.
formZ 4.5 adds a new API and script language and also introduces new features including healing, custom attributes and bill of materials, smooth text and OpenGL API-based smooth interactive shading.
This article will go from installing and setting up a BREW development environment and emulator, through to getting an OpenGL ES system up and running and displaying a single triangle. From there existing OpenGL API resources can take you further into the process of developing your 3d application. This tutorial is particularly timely given the OpenGL ES 1.1 Coding Challenge beginning Sept 17th.
Notes3D lets you view, share and document your 3D CAD models using the OpenGL API for rendering.. While Notes3D has typical viewer capabilities, the real power of Notes3D is in its ability to document the 3D model by adding text and hyperlinks to parts, steps and snapshots, and then publish (on or offline). It also support different render styles.
RenderMonkey is a full featured shader editor for rapid prototyping of shaders. This major v1.5 update includes full support for OpenGL 1.5 and the OpenGL Shading Language. It also includes a number of improvements to the shader creation workflow and a number of new features. The integrated shader compiler and preview window provide immediate visual feedback. The SDK supports the creation of custom importers and exporters.
OpenGL ES, OpenML, OpenVG, OpenMAX lectures and training sessions - London Sept 01, Helskinki Sept 1
Khronos is launching the Khronos Developer University Lecture series which features presentations and practical tutorials focused on the mobile and desktop graphics standards for OpenGL ES (OpenGL for mobile devices), OpenML (video & graphics I/O and handling), OpenVG (vector graphics acceleration), and OpenMAX (acceleration for media primitives). The first 2 lecture events are free in London (Sept 1 ‘04) and Helsinki (Sept 17 ‘04), followed by international locations through the next 6 months.
Tutorial on rendering particles using the GL_ARB_point_parameters and GL_ARB_point_sprite extensions
In particle engines using a quad to render geometry, it is computationally expensive for each particle to billboard the face and then send 4 points and 4 textures coordinate to video cards. The GL_ARB_point_parameters and GL_ARB_point_sprite offer a fast and easy way for rendering particles. This tutorial explains how to use points rather than quads.
JAD is a tile based Maze-RPG, using the OpenGL API for graphics and SDL for input and sound. The new release includes sample code for a pong game with simple collision detection, getting input for a map grid, and an example how to implemet a turn based game in a game loop which allows animation at the same time.
FSC is a game which uses SDL for input handling and the OpenGL API for display. This alpha version adds simple slider boxes and is the first playable version.
This is a demo of terrain LODs geomorphing using OpenGL 1.5 vertex shaders. It includes realistic water and pseudo-AI to control the camera.
VRMesh is a new style of sketch-based free-form 3D polygonal parametric modeling software using the OpenGL API for rendering. It creates an object directly from a sketched curve, represents the object with a two-manifold triangle mesh, and also provides a bundle of mesh editing tools to modify objects indirectly or directly on the triangle mesh (i.e. just sketching a curve, you will get an editable 3D model).
Fusion is a digital media pipeline language that also takes advantage of an advanced node-based compositing engine. It permits composite planes transformable in 3D space, but also allows 2D objects to move along spline paths in XYZ space. (e.g. to have text deform on a circular path around another object with occlusion, simply draw a circular spline oriented in 3D space and attach a text object to it). The new Fusion 5 previewed at Siggraph adds OpenGL API-accelerated rendering, camera path import, and masking and B-spline enhancements.
