Requirements:

• OpenGL, GLUT, GLEW
• CMake
• CUDA 2.2 minimum (>=4.0 for Multi-GPU) with SDK

Compilation:

• Modify SDK path in (src/CMakeLists.txt) to point to yours
• Then run:

   mkdir build; cd build;
   cmake ..;	
   make;
  

Running:

./cudagl [-n=<numParticles>] [-devices=<numDevices>]

• eg. ./cudagl -n=1024 -devices=1 (To simulate 1024 particles across 1 device)

Controls:

• 'spacebar' plays/pauses the simulation

• 'ctrl+mouse_scroll' zooms in/out

• 'mouse_left+mouse_move' moves camera around

• 'd' loops through the particle display modes

• 's' toggles between a skybox and a ground surface

• 'b' displays the bounding box

• '`' hides/shows the parameter UI

• 'p' toggles picture mode

• 'm' toggles model mode

• 'u' toggles uber mode

• '1' resets particles to a random position

• '2' resets particles to the center of the grid

• 'Esc' exits the program

Data:

• New pictures (.ppm) can be placed in 'src/data'
• New 3DS models can be placed in 'src/load3ds/models/'
