Lumo

Lumo is a realtime lab software arount 3D models

why this name ?

Lumo is "Light" in Esperanto, its a short and pretty word to me :)

Goals :

Implement all realtime rendering Algo used in Games / realtime Presentation softwares
Mastering all theses tech for learning purposes
Implement my own idea ( by ex related to SubSurface Scatering, or Shadows )
Implement a modern use of 3D vulkan Api, and Node Graph related stuff
Can Render mesh's or sdf's in the same way
And finally can export rendering to picture, video, and maybe a self little portable binary form to be used everywhere
Implement some specific VFX algo by plugigns like (compute based mesh sim, morphogenesis, sdf meshing)
all these algos at max as possible in GPU only (include mesh generation)

at least, support all rendering features and result of the SketchFab Renderer (yes im loving it haha)

Gettings Started

Create a new project (automatically saved when you quit the soft for the moment for easier dev)
Click right in the graph and add nodes.
Left mouse double click on a texture slot (Orange) of nodes for show the result in the 3d viewport
Middle mouse double click on a texture slot (Orange) of nodes for show the result in the 2d viewport
select a node and you can tune it in the tuning pane

thats all

How to build

Build dependencies

Vulkan SDK 1.2 at least : latest and a compatible GPU
Python 3.7 at least : latest

Succesfully Tested with Vulkan SDK 1.3.224.1

Cmake

You need to use cMake. You can use the gui (my prefered way). but, if you run cmake by command line, For the 3 Os (Win, Linux, MacOs), the cMake usage is exactly the same,

Choose a build directory. (called here my_build_directory for instance) and
Choose a Build Mode : "Release" / "MinSizeRel" / "RelWithDebInfo" / "Debug" (called here BuildMode for instance)
Run cMake in console : (the first for generate cmake build files, the second for build the binary)

cmake -B my_build_directory -DCMAKE_BUILD_TYPE=BuildMode cmake --build my_build_directory --config BuildMode

Some cMake version need Build mode define via the directive CMAKE_BUILD_TYPE or via --Config when we launch the build. This is why i put the boths possibilities

Platforms Support

all libs and code used here are cross platform, so compatible (win, linux).

The mac platform is not supported for the moment, due to the vulkan driver. Could be tested at some stage with the Molten-VK implementation..
