Note: CMake MODELS_DOWNLOAD_DISABLED is ON by default so you don't get stuck in cmake downloading the heavy 3D models that this demo can use. Unchecking it will download 8 models in a local folder called downloaded_resources. I could take time...
This sample shows how to use NVIDIA command-list extension over basic scenes
The sample uses a pre-baked binary format (bk3d) for various models coming from CAD applications.
The main file 'gl_commandlist_bk3d_models.cpp' shows how to setup command-list on simple geometries such as the floor grid and the target cross. It is a good starting point to understand how to use command-lists
The second file 'gl_commandlist_bk3d.cpp' contains everything related to bk3d: it will load, setup and display data coming from this file format.
This samples can either run in MSAA mode but also in 'supersampled' mode (see NVFBOBox)
##Command-line arguments
- -v \n-m
- -c 0 or 1 : use command-lists
- -b 0 or 1 : use bindless when no cmd list
- -o 0 or 1 : display meshes
- -g 0 or 1 : display grid
- -s 0 or 1 : stats
- -a 0 or 1 : animate camera
- -i : use a config file to load models and setup camera animation
- -d 0 or 1 : debug stuff (ui)
- -m : load a specific model
- : load a specific model
- -q : MSAA
- -r <ss_val> : supersampling (1.0,1.5,2.0)
###Examples on arguments
load a scene and start animation:
gl_commandlist_bk3d_models.exe -i scene_car.txt -a 1
(Note: CMake MODELS_DOWNLOAD_DISABLED should be OFF and you should have downloaded the other models thanks to cmake if you want scene_car.txt and scene_ds_models.txt to work...)
load a bk3d file:
gl_commandlist_bk3d_models.exe -m SubMarine_134.bk3d.gz
or
gl_commandlist_bk3d_models.exe SubMarine_134.bk3d.gz
##in app toggles
- 'h': help
- space: toggles continuous rendering
- 'c': use Commandlist
- 'e': use Commandlist EMULATION
- 'l': use glCallCommandListNV
- 'o': toggles object display
- 'g': toggles grid display
- 's': toggle stats
- 'a': animate camera
##Scene from external file (-i) This is a simple description made of:
- a list of bk3d objects to load
- a list of position-target coordinates for the camera animation
<num of filenames>

<num of camera coords>
