/CUDA-OpenGL-Basic-Interaction

Primary LanguageC++

Setup

Windows

  1. Install CUDA toolkit from here. Note: lib has been tested with CUDA 11.04
  2. Go to 'C:\ProgramData\NVIDIA Corporation\CUDA Samples\v11.4'
  3. Copy the 'common' folder into this repo

Clion

Cmake

  1. open the project in Clion as 'Cmake project'
  2. compile the programm. Note that execution will fail.
  3. from the 'C:\ProgramData\NVIDIA Corporation\CUDA Samples\v11.4\bin\win64\release' folder copy the 'freeglut.dll' and 'glew64.dll' into the './cmake-build-debug' folder created by clion
  4. Run the programm again and now it should execute

Visual Studio 2019

New Visual Studio Project (optional)

Only needed if you do not want to use the included .vcxproj file.

  1. create a new CUDA project. Here v11.4
  2. From 'C:\ProgramData\NVIDIA Corporation\CUDA Samples\v11.4' copy the 'bin' folder into this repo
  3. Open the properties of the Solution
  4. 'Configuration Properties >> C/C++ >> General' in 'AdditionalIncludeDirectories' add ';common/inc'
  5. 'Configuration Properties >> Linker >> General' in 'Additional Library Directories' add ';common/lib/$(PlatformName)'
  6. 'Configuration Properties >> Linker >> Input' in 'Additional Library Directories' add 'glew64.lib'
  7. 'Configuration Properties >> General' change 'Output Directory' to '$(ProjectDir)bin/win64/$(Configuration)/'
  8. For Visual Mode go to: Project > Properties > Configuration Properties > C/C++ > Preprocessor > Preprocessor Definitions and add SIMVIZ

Existing Visual Studio Project

  1. Just open the included CUDA-OpenGL-Basic-Interaction.vcxproj file
  2. For Visual Mode go to: Project > Properties > Configuration Properties > C/C++ > Preprocessor > Preprocessor Definitions and add SIMVIZ

Linux

  1. sudo apt install nvidia-cuda-toolkit
  2. sudo apt-get install freeglut3-dev
  3. sudo apt-get install libglew-dev
  4. sudo apt-get install libglfw3 libglfw3-dev (???)

Use CMake

  1. mkdir build to create a build folder
  2. cmake .. or use cmake -DHEADLESS=FALSE -DDEBUG=FALSE .. see Options

Installing latest CUDA version (optional)

see the cuda instalation guide

Options

Change the resolution in interactions.h.

Headless or Visual Mode

Headless mode will not visualize the data and therefore does not need the corresponding libraries. Can be used for performance measurement without OpenGL or for using the data otherwise.

Activate by defining HEADLESS.

For cmake compile with cmake -DHEADLESS=TRUE ..

For Visual Studio go to: Project > Properties > Configuration Properties > C/C++ > Preprocessor > Preprocessor Definitions and remove SIMVIZ

Debug Mode

Activate by defining DEBUG.

For cmake compile with cmake -DEBUG=TRUE ..

For Visual Studio go to: Project > Properties > Configuration Properties > Debugging > Environment and add DEBUG
