Building

You must download Visual Studio IDE and install the C++ package. Now you can open directx11-playground.sln and build the app with f5.

Examples

Basics

Triangle

A simple triangle. The only example that does not use indexed drawing.

Rotating cube

A rotating colored cube. Each face is independant so that the colors can be applied without smearing.

Textured primitives

Show some procedurally-generated primitives with their UV maps.

Model loading

Loads a GLTF model with its texture.

[WIC] Skybox

Show an environment in the background using a cubemap.

[WIC] Global GUI

Display a grid, some icons for the lights and a dynamic gizmo to always know the orientation of the camera.

Blinn-Phong shading

Directional light

Setup a simple scene with a directional light and no material. A menu is available to edit ambient, diffuse and specular properties.

[WIC] Multiple light types

Uses multiple point, directional and spotlights.

[WIC] Materials

Uses different objects with different materials applied to them to compare how they react to lighting.

Non-Photorealistic Rendering (NPR)

[WIC] Gooch shading

Change pixel color value from "cool to warm" based on normal direction angle from the camera.

[WIC] Toon shading

A rendering technique closer to traditional 2D animation.

Intermediate

[WIC] Object picking

Select objects on the scene with the mouse and raytracing.

[WIC] View frustrum culling

Do not render objects outside of the camera view.

[WIC] Occlusion culling

Do not render objects hidden by other ones.

[WIC] High Dynamic Range

Allows a rendered image to show more details when the scene contains both shadows and highlights.

[WIC] Gamma correction

Fix the gamma of the screen.

[WIC] Normal mapping

Show micro-geometry with lighting based on a texture.

[WIC] Parallax mapping

Adds micro-geometry to a model based on a texture.

Physically based rendering (PBR)

[WIC] Directional light

Base exemple of PBR.

[WIC] Multiple light types

Test multiple light types with PBR.

[WIC] Materials

Uses PBR materials.

[WIC] Image based lighting (IBL)

Local illumination technique based on the scene.

[WIC] Screen-space subsurface scattering (SSS)

Shows hows lights can traverse some materials.

[WIC] Hair

Render hair and fur.

Shadows

[WIC] Directional shadow mapping

Shadows created by a directional light.

[WIC] Point shadow mapping

Shadows created by point lights.

[WIC] Screen space ambient occlusion (SSAO)

Adds more shadows to micro-geometry based on vertex density.

[WIC] Light map

Baked global illumination based on raytracing.

Animations

[WIC] Linear transform

Basic translation and rotation loaded from gltf.

[WIC] Squeletal animation

A basic character movement loaded from gltf.

Post-Processing

[WIC] Bloom

Show a light with bloom effect.

[WIC] Depth of field

Blur the out of focus area of the image.

[WIC] Motion blur

Blur based on movement of the camera.

Advanced

[WIC] Particle system

Shows emissive particles.

[WIC] Instanced rendering

Render a forest.

[WIC] Tesselation

Shows how an object contains more or less geometry based on camera distance.

[WIC] Deferred shading

Improve lighting performance with geometry buffer.

[WIC] Deferred plus shading

Improve lighting performance in a forward shading pipeline by dividing the screen on multiple areas.
