This module contains tutorials and sample applications intended to demonstrate the usage of Diligent Engine. The module depends on the Core and Tools submodules.
To build and run the applications in the module, please follow the instructions in the master repository.
This tutorial shows how to render simple triangle using Diligent Engine API.
This tutorial demonstrates how to render an actual 3D object, a cube. It shows how to load shaders from files, create and use vertex, index and uniform buffers.
This tutorial demonstrates how to apply a texture to a 3D object. It shows how to load a texture from file, create shader resource binding object and how to sample a texture in the shader.
This tutorial demonstrates how to use instancing to render multiple copies of one object using unique transformation matrix for every copy.
This tutorial demonstrates how to combine instancing with texture arrays to use unique texture for every instance.
This tutorial shows how to generate command lists in parallel from multiple threads.
This tutorial shows how to use geometry shader to render smooth wireframe.
This tutorial shows how to use hardware tessellation to implement simple adaptive terrain rendering algorithm.
This tutorial shows how to render multiple 2D quads, frequently swithcing textures and blend modes.
This tutorial shows dynamic buffer mapping strategy using MAP_FLAG_DISCARD and MAP_FLAG_DO_NOT_SYNCHRONIZE
flags to efficiently stream varying amounts of data to GPU.
This tutorial demonstrates different ways to update buffers and textures in Diligent Engine and explains important internal details and performance implications related to each method.
This tutorial demonstrates how to render a 3d cube into an offscreen render target and do a simple post-processing effect.
This tutorial demonstrates how to render basic shadows using a shadow map.
This tutorial shows how to implement a simple particle simulation system using compute shaders.
This tutorial demonstrates how to use Diligent Engine to render to multiple windows.
This sample demonstrates how to integrate Epipolar Light Scattering post-processing effect into an application to render physically-based atmosphere.

This sample demonstrates how to use the Asset Loader and GLTF PBR Renderer to load and render GLTF models.
This sample demonstrates how to integrate the Shadowing component into an application to render high-quality shadows.
Please refer to Build and Run Instructions section in the master repository's readme.
Command line options:
- -mode {d3d11|d3d12|vk|gl} - select rendering back-end (exmple: -mode d3d12).
- -width value - set desired window width (example: -width 1024).
- -height value - set desired window height (example: -height 768).
- -capture_path path - path to the folder where screen captures will be saved. Specifying this parameter enables screen capture (example: -capture_path .).
- -capture_name name - screen capture file name. Specifying this parameter enables screen capture (example: -capture_name frame).
- -capture_fps fps - recording fps when capturing frame sequence (example: -capture_fps 10). Default value: 15.
- -capture_frames value - number of frames to capture after the app starts (example: -capture_frames 50).
- -capture_format {jpg|png} - image file format (example: -capture_format jpg). Default value: jpg.
- -capture_quality value - jpeg quality (example: -capture_quality 80). Default value: 95.
- -capture_alpha value - when saving png, whether to write alpha channel (example: -capture_alpha 1). Default value: false.
When image capture is enabled the following hot keys are available:
- F2 starts frame capture recording.
- F3 finishes frame capture recroding.
- F4 saves single screenshot.
To record multiple frames after the app starts, use command line like this:
-mode d3d12 -capture_path . -capture_fps 15 -capture_name frame -width 640 -height 480 -capture_format png -capture_frames 50
