cycles's Introduction

Cycles Renderer

Cycles is a path tracing renderer focused on interactivity and ease of use, while supporting many production features.

https://www.cycles-renderer.org

Building

Cycles can be built as a standalone application or a Hydra render delegate. See BUILDING.md for instructions.

Examples

The repository contains example xml scenes which could be used for testing.

Example usage:

./cycles scene_monkey.xml

You can also use optional parameters (see ./cycles --help), like:

./cycles --samples 100 --output ./image.png scene_monkey.xml

For the OSL scene you need to enable the OSL shading system:

./cycles --shadingsys osl scene_osl_stripes.xml

Instructions for updating ccycles.dll

How to Update ccycles.dll Properly

Ensure both the Mac and the Windows sections are completed.

Mac

For Apple Silicon devices:
- Ensure you have the universal binaries. Download them here.
- Unzip the binaries to RDK/cycles/lib/darwin_universal.
For non-Apple Silicon devices:
- Navigate to RDK/cycles/cycles.
- Run the command make update.
Go to RDK/cycles/cycles and run make release.
Execute cp -r install/* ../../../../../../big_libs/RhinoCycles/ccycles/osx/release/.
Go to big_libs, create a branch if needed and execute:

git add -f RhinoCycles/ccycles/osx/release/libccycles.dylib
git commit
git push <branch_name>

Windows

Checkout the big_libs branch made above.
Navigate to RDK/cycles/cycles.
Execute rm -fr build/.
Run ./make_rhino.bat release all.

This will end with a build error.

Open Cycles.sln.

Switch the target to Release.
Right-click the cycles_device project and select Open folder in File Explorer.

Open cycles_device.vcxproj with a text editor.

Search for the string /J /bigobj.
Ensure you found the one for the Release target and change it to /J /bigobj /Zc:__cplusplus.

Go back to Cycles.sln, reload the project, and then press Build.
After the build is finished, explicitly build the INSTALL project.
Download ResourceHacker if you haven't and ensure the executable is in Windows' PATH.
Navigate to RDK/cycles with PowerShell and execute the script:

.\versioninfo_changer.ps1

Copy the following two files:

RDK/cycles/cycles/install/ccycles.dll
RDK/cycles/cycles/install/cycles_kernel_oneapi_jit.dll

To the following folder: big_libs\RhinoCycles\ccycles\win\release

Go to big_libs and execute:

git add -f RhinoCycles/ccycles/win/release/ccycles.dll RhinoCycles/ccycles/win/release/cycles_kernel_oneapi_jit.dll
git commit
git push

cycles's Issues

Errors in https://github.com/mcneel/CCSycles

Hi,
I followed the steps in https://github.com/mcneel/CCSycles to build. But there are errors.
Few projects are not even loaded (because they do not exist).

Please help me to build the solution. I have been struggling.

What are server and cubin?

Hi,
What are server and cubin?

Can I make cycles run as a server and send requests from my application to perform tasks like rendering and baking?

Thank you

[BUILD][CMake] OPENEXR_HALF_LIBRARY and OPENEXR_ILMIMF_LIBRARY are set to `NOTFOUND`

On my gentoo system, I have all the dependencies (e.g. the aforementioned opener)

[ebuild   R    ] media-libs/openexr-3.1.4-r1

I'm not sure what extra to openexr I need to install to get these variables to be not empty. For example, searching for ILMIMF returns nothing relevant to me.

Any suggestions on what Libs do I need to install, even if one could link the source to the respective libraries?

Please provide example code to bake textures

Hi,

Mine is a basic 3D CAD drawing application written in C++
I am trying to integrate cycles in my application. I could build cycles scene and session in memory. Now I need to bake textures of each object and export the scene. I could not find how to bake textures. Spent more than a year but no luck. Tried exploring how blender is doing but lost in its RNA and python stuff.

Can you please provide a code sample?
Thanks in advance.

CMake errors

Hi,
I have been struggling to build the project

I have downloaded all the folders under https://svn.blender.org/svnroot/bf-blender/trunk/lib/win64_vc14/ and copied to lib folder. It is more than 3.2 GB

Downloaded other software like GLUT, GLEW etc and copied to the lib folder. Still I am getting many build errors.

Cant we make the build process simple? A baking library is depending on external software sized more than 3 GB? Am I doing anything wrong?
