Say you make a typo (like, missing a semicolon) and go to build your shader. This will work fine if you can write perfect code, but if you make mistakes, you'll find that this part is a huge headache.
#Resolume arena 5 tutorial code
One way you can start writing your effects is to just come into this frag shader code and start making edits. Make sure SetMinInputs and SetMaxInputs reflect the number of inputs you're using. The function SendParams is going to take care of setting uniform variables and all the stuff you'd expect to do to get your shaders and your variables connected.

That is actually all you have to do to get the parameter set up. To do that, just add a parameter like this:ĪddParam( ffglqs::Param::Create( "Sensitivity" ) ) It ranges from 0 to 1, very straightforward. Let's go into the constructor here and we'll replace the RGB sliders with a simple float parameter. Sed -i "s/AddSubtract/$1/g" build/windows/$1.vcxprojĬp -r source/plugins/AddSubtract source/plugins/$1 Sed -i "/ProjectGuid/d" build/windows/$1.vcxproj CamelCase, no spacesĬp build/windows/AddSubtract.vcxproj build/windows/$1.vcxproj If you have Git Bash installed or some other bash-like command prompt, try running this function from the FFGL repository directory (subbing "Vignette" for the name of your plugin): # first parameter is the effect filename to use. You can follow the steps here: Create your first plugin Go to Preferences->Video and make sure that Resolume's looking in the right folder for your FFGL plugin. Let's take the effect AddSubtract and go ahead and build it (by right-clicking the project file and clicking Build). Next, let's export one of the example plugins just to make sure we can do this process from start to finish.
#Resolume arena 5 tutorial how to
I'm going to focus on effects since that should give you an idea of how to use textures and variables controlled by Resolume. effects have one input texture, and mixers have two or more input textures. sources are also known as generators - they take no texture input and create an output just from the code you write. Once it's imported, you can see the folders here for the different types of plugins you can create. Running the ExamplesĬheck out the repo above and open up the included solution file at build/windows/FFGLPlugins.sln You'll also need Git and Visual Studio installed. This has helped me with basically everything I do with computer graphics even if I'm not directly using either OpenGL or C++. However, if you really want a good foundation, I highly recommend this book, Computer Graphics Programming in OpenGL with C++. If you're looking for online resources, I recommend The Book of Shaders. You don't need to be an expert, but you'll want to have some basic familiarity with concepts like vertex shaders, fragment shaders, and texture mapping. To get the most out of this tutorial, you'll want some familiarity with OpenGL and C++.
