Introduction

This page explains how to build exposure render with Visual Studio 2017

Dependencies

Exposure render depends on: CUDA, Qt and VTK.

Versions used in this update:

  • CUDA 9.2
  • Qt 5.11.1
  • VTK 7.1.1
  • Microsoft Visual Studio 2017

CUDA

You can skip this step if you already have the CUDA SDK and toolkit installed

The necessary installers can be downloaded from: http://developer.nvidia.com/cuda-toolkit-40

  • Download and install the GPU Computing SDK
  • Download and install the CUDA Toolkit
  • Download and install the developer drivers

Qt

Skip this step if you already have installed Qt

  • Download the Qt installer from: https://www.qt.io/download-qt-installer
  • Under Qt->5.11.1, Make sure you check the box for MSVC 2017 64-bit
  • Add an environment variable called QTDIR and set it to <install dir>\5.11.1\msvc2017_64

VTK

VTK must be compiled with Qt support

  • Download the VTK 7.1.1 sources from the VTK website: http://www.vtk.org/VTK/resources/software.html
  • Extract the zip file (for instance c:\VTK\7.1.1)
  • Run CMAKE and set the source dir to the VTK root dir
  • Make sure to use the 64-bit compiler
  • Make sure to check the Qt check box in the VTK settings
  • For the GUI to run you need to build VTK with GUI support
  • See https://www.vtk.org/Wiki/VTK/Configure_and_Build for additional info/help
  • You might also consider to build the examples
  • Generate the Visual Studio 2017 solution files
  • Open the generated solution and build it, RelWithDebugInfo is advised

Exposure Render

  • Run CMAKE and set the source dir to the Exposure Render Source dir
  • Make sure to select the 64-bit compiler.
  • After building, copy the presets directory from the source dir to the build dir.

Notes

  • It might be required to update the maximum MVC version number in CUDA code.:
    • In <CUDA_install_dir>\NVIDIA GPU Computing Toolkit\CUDA\v9.2\include\crt\host_config.h
    • Change the right hand side of the equation: "#if _MSC_VER < 1600 || _MSC_VER > 1914" to a version number high enough to include your used Visual Studio version
  • In order to run Exposure Render from Visual Studio, you might have to set ExposureRender as the startup project.
  • Executable might not start due to missing DLL's:
    • Copy all the dll files from <VTK_build_dir>bin\Debug to <ExposureRender_build_dir>\debug
    • Copy Qt5Cored, Qt5Guid, Qt5Widgetsd, Qt5Xmld dll from <Qt_install_dir>\5.11.1\msvc2017_64\bin to <ExposureRender_build_dir>\debug
  • Examples folder, Icons folder, ReadMe.txt and contents of presets folder from Exposure Source directory might also have to be copied to <ExposureRender_build_dir>\debug
  • Currently GPU Capability is set to 5.0. If incompatible with your GPU Capability (Can be seen on startup screen of Exposure Render):
    • In CMakeLists.txt:
    • Change 'SET(CUDA_NVCC_FLAGS "-arch=sm_50;${CUDA_NVCC_FLAGS}")', to 'SET(CUDA_NVCC_FLAGS "-arch=sm_XX;${CUDA_NVCC_FLAGS}")', where XX is your Capability.
