Osprey is an open source plugin that integrates the OSPRay renderer and Rhino 3D modeler. OSPRay is an "open source, scalable, and portable ray tracing engine for high-performance, high-fidelity visualization on Intel Architecture CPUs."

This plugin is in the early stages of development.

Intel OSPRay: https://www.ospray.org/

Download the 0.2.0 release for Rhino 6 on Windows: https://github.com/darbyjohnston/Osprey/releases/download/v0.2.0/Osprey-0.1-rh6-win-x64.rhi

Install the plugin by starting Rhino and dragging and dropping the plugin file onto the Rhino application.

To use the plugin change the current renderer in Rhino to "Osprey". There are some render settings in the "Osprey" section of the "Rendering" panel.

• Renderer - The name of the renderer to use.
• Passes - The number of passes to render.
• Preview passes - The number of low resolution preview passes to render before the main passes.
• Pixel samples - The number of pixel samples.
• AO samples - The number of ambient occlusion samples.
• Denoiser - Enable denoiser post-processing.
• Tone mapper - Enable tone mapping post-processing. If this is enabled the "Gamma" setting in "Dithering and Color Adjustment" should be set to 1.0.
• Exposure - Exposure setting for the tone mapper.

These scenes are from data sets of New York City provided by BYTES of the BIG APPLE: https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-nyc-3d-model-download.page

The scene MN01 consists of 132255 model components with a file size of about 350MB: https://www1.nyc.gov/assets/planning/download/zip/data-maps/open-data/nyc-3d-model/nyc_3dmodel_mn01.zip

The scene MN08 consists of 366474 model components with a file size of about 950MB: https://www1.nyc.gov/assets/planning/download/zip/data-maps/open-data/nyc-3d-model/nyc_3dmodel_mn08.zip

The scenes were opened in Rhino and modified with the following:

• Added a sun
• Added a ground plane
• Added a new material for the buildings
• Enabled the skylight with an intensity of 0.3 and the default custom environment
• Enabled curve rendering
• Set the render gamma to 2.2 and enabled the linear workflow
• Set the backdrop to the solid color: 65, 100, 170

OSPRay renderer settings:

• Resolution: 1920x1080
• Passes: 8
• Pixel samples: 1
• Ambient occlusion samples: 16
• Denoiser: Enabled
• Building diffuse color: 140, 160, 175

Rhino 6 renderer settings:

• Resolution: 1920x1080
• Quality: Good
• Building diffuse color: 220, 240, 250

Rhino 7 WIP renderer settings:

• Resolution: 1920x1080
• Quality: Good
• Building diffuse color: 220, 240, 250

Requirements:

• Visual Studio 2017
• Rhino 6 SDK - https://www.rhino3d.com/download/Rhino-SDK/6.0/release
• Git - https://git-scm.com/
• CMake - https://cmake.org/

Open a Visual Studio 2017 x64 Native Tools Command Prompt. Choose a directory and clone the repository:

> git clone -b https://github.com/ospray/ospray.git

Create a directory for the build and run CMake:

> mkdir ospray-build
> cd ospray-build
> cmake ../ospray/scripts/superbuild -G "NMake Makefiles" -DINSTALL_IN_SEPARATE_DIRECTORIES=FALSE -DBUILD_OIDN=TRUE -DBUILD_OIDN_FROM_SOURCE=FALSE

Start the build:

> nmake

After the build is finished OSPRay will be installed in the "install" sub-directory.

Open the control panel and add a new environment variable called "OSPRAY_INSTALL". Set the value to the full path of the "install" sub-directory.

Open a Visual Studio 2017 x64 Native Tools Command Prompt. Choose a directory and clone the repository:

> git clone https://github.com/darbyjohnston/Osprey.git

Open the "Osprey.sln" file with Visual Studio 2017 and start debugging. When the build has finished Rhino will start automatically.

Install the Osprey plugin from the menu "Tools/Options...". The plugin is named "Osprey.rhp" and is located in the sub-directory "x64\Debug" or "x64\Release" depending on your build configuration. Note that if you change the build configuration you will need to reinstall the plugin.

Tag the git repository:

> git tag -a v0.3.0 -m "Version 0.3.0"
> git push origin v0.3.0

A RHI package is generated automatically as part of the project's build events. Add the package to the release page on GitHub.

Bump the version numbers in this README.

Bump the version number in Visual Studio:

• Change the configuration to "Release"
• Right click the "Osprey" project and click "Properties"
• In the dialogs that pops-up, click "Build Events/Post-Build Event"
• Edit the command-line to reflect the new version number

The following steps provide an example of how to make changes to the code.

Fork the repository using the GitHub website and clone it to your local machine:

> git clone https://github.com/you/Osprey.git
> cd Osprey

Add the upstream repository to keep your source code up to date:

> git remote add upstream https://github.com/darbyjohnston/Osprey.git

Create a new branch for your work:

> git checkout -b mychange

Fetch and merge the latest changes:

> git fetch upstream
> git merge upstream/master

When making your change please follow the coding convention and style of the file you are working in.
