Detailed Description

Geometry represents 2D coordinate data that you can use to render 2D nodes and text.

When rendering using Geometry, create the Geometry object beforehand instead of allocating it on the spot. Because Geometry inherits GPUResource, it needs to register into the resource manager after creation. Combined with memory allocation, this is a relatively expensive operation.

To render 2D coordinate data using Geometry:

// Create Geometry.
// If possible, do this only once and reuse the Geometry.
GeometrySharedPtr geometry = Geometry::create(domain);
// Declare a quad of size 40x30.
QuadDescription quad(Vector2(0.0f, 0.0f), Vector2(40.0f, 30.0f));
geometry->setGeometry(*renderer, quad);
// Make a transformation that translates an object 50 units to the right.
Matrix4x4 transform = Matrix4x4::createTranslation(50.0f, 0.0f, 0.0f);
// Bind the material (there are multiple ways to do this).
material->getShaderProgram()->bind();
// Draw the geometry.
geometry->drawUntextured(*renderer, transform, GraphicsPrimitiveTypeTriangleStrip, *material);
Since
Kanzi 3.9.4 inherits from GPUResource.
