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.
