Qt 3D: Advanced Custom Material QML Example#
Demonstrates creating advanced materials in Qt3D.
This example demonstrates creating advanced custom materials.
Running the Example#
To run the example from Qt Creator, open the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example.
Description#
Advanced custom material example shows more complex shaders, and demonstrates controlling your shader properties with QtQuick user interface and Animation. Water is a 3D mesh, that is modeled and uv mapped inside Blender, and then brought into Scene 3D as an .obj file. Shader properties that user can control, are defined in advancedcustommaterial/WaterMaterial.qml.
Controls#
Texture scale slider#
Multiplies texture coordinates inside the vertex shader. Controls the size of the textures on water surface.
Texture speed slider#
Offsets values for texture coordinates which are animated in advancedcustommaterial/Water.qml and then passed to vertex shader. Creates the effect of textures scrolling over the surface.
Specularity#
Multiplies specular texture values inside fragment shader. Makes the water reflective.
Distortion#
Multiplies the offset in red and blue channels of wave texture in fragment shader. Makes the surface textures animate more randomly.
Normal amount#
Multiplies the normal map values inside fragment shader. Controls the visibility of smaller waves on the water surface.
Wave speed#
Modifies the frequency of the sine wave inside vertex shader. Controls the speed of the waves.
Wave height#
Multiplies the vertex Y position inside vertex shader. Controls the height of the waves.
Mesh rotation#
Rotates the water mesh in advancedcustommaterial/Water.qml.
