Free surfaces software for mac

Tux Racer lets you take on the role of Tux the Linux Penguin as he races down steep, snow-covered mountains. Enter cups and compete to win the title! Tux Racer includes a variety of options for gameplay, including the ability to race courses in fog, at night, and under high winds.
Your journey starts as you compete on local courses. Win and you will unlock other courses and cups that will lead you to more exciting and challenging races. Only the quickest, smartest, and luckiest will win!
Main features:
- Fun, easy to learn
- Exciting 3D courses
- Sophisticated physics result in thrilling rides down the mountains
- Collect herring while avoiding obstacles for high scores
- Race over a variety of surfaces, including fluffy snow and slick ice
- Race in various weather conditions and lighting conditions
- Create your own courses using any paint program such as The GIMP (no 3D modeller required)
- Suitable for all ages.
Enhancements:
- This release fixes an issue in the TuxRacer sources that surfaced due to a change in Apples GLUT Framework in Mac OS X 10.2 (Jaguar). There are no other changes.

SoundField is a visual audio mixer. It displays sounds as circular surfaces.
The graphical representation of sound brings concepts to audio that are traditionally more related to other fields, such as proximity, boundary, overlap and placing.
Enhancements:
- Created distributed version.
- Minor interface changes.

FireCracker is a highly configurable fireworks screensaver. Lets you configure gravity, air resistance, explosive force, particle surface area, the works.
Internally, its an advanced particle simulation based on real-world physics that you can control.
Enhancements:
- Fixed a stupid bug where the preferences were not saved, thus resulting in a smaller display of fireworks than the user might expect.

Strichzeichner 0.8 is a simple to use, yet sophisticated painting program especially which creates views of metallic surfaces.

It will help you to draw a front view of the desired surface. Drawing a surface means to draw many lines at different colours in the same direction. The direction, the colour and the length of the lines can be changed during the drawing process.

The drawing itself is fully pattern oriented. This innovation is especially important for Web Designers and Game Developers who need access to metallic surfaces. Use this application only to generate some basic patterns that can be modified in other applications (like Photoshop) for best results.

Creating surfaces in a greyscale colour space: You can choose between two methods of painting the surface. The first method draws continuously three lines in three different colours. The second method draws continuously only one gradient line. The colour of the lines can be adjusted through the whole greyscale.

Creating surfaces in a RGB colour space: Each line can be subdivided with 16 moveable markers in 17 different regions. Each region will be filled with a gradient similar to the colour of the enclosing markers. Each painted line considers exactly these gradients. It is now possible to draw directly the complete area by pressing the OneShot- Button. The OneShot- Function is currently limited to horizontal lines.

Using the LFO as a modulating source for the line length: A special LFO (Low Frequency Oscillator) can be activated in order to change the length of the lines at real-time. Its frequency can be adjusted up to two Hertz. The generated Images can be saved as Bitmap File or exported in various formats if QuickTime Pro is installed.

Note: If you are wondering about the difference between the generated Images and Digital Noise, here is the answer: The only difference is a piece of control you get when using the Strichzeichner application.

Feedback illustrates how to create a warping feedback effect (ala G-Force or Fractogroovalicious,) in OpenGL by rendering the screen to a texture and applying that texture to a wapring surface.

C++ source code using OpenGL / GLUT is included.

The Download - Feedback with source (for Mac OS X, tricky to compile in windows due to bugs in MS Visual Studio glut.h).

Raster3D is a set of tools for generating high quality raster images of proteins or other molecules. The core program renders spheres, triangles, cylinders, and quadric surfaces with specular highlighting, Phong shading, and shadowing.

It uses an efficient software Z-buffer algorithm which is independent of any graphics hardware. Ancillary programs process atomic coordinates from PDB files into rendering descriptions for pictures composed of ribbons, space-filling atoms, bonds, ball+stick, etc.

Raster3D can also be used to render pictures composed in other programs such as Molscript in glorious 3D with highlights, shadowing, etc. Output is to pixel image files with 24 bits of color information per pixel.
