SHANGHAI – October 29, 2026 -- VeriSilicon (688521.SH) has launched GLTiny, a 3D GPU programming model that pairs a streamlined API with an ultra-lightweight driver for smartwatches, smart glasses and other wearables with tight power and memory budgets. GLTiny runs on the company's Nano OpenGL ES GPU IP series.
GLTiny cuts driver memory footprint and CPU overhead through configurable rendering
The model draws on VeriSilicon's experience in wearable graphics. Developers define their rendering requirements through configurable functions, and GLTiny maps them onto the underlying OpenGL ES GPU capabilities. VeriSilicon says this reduces driver memory footprint and CPU overhead, improving power efficiency and performance on constrained hardware.
Native glTF support covers lighting, skinning, morph targets and animation
GLTiny renders standard glTF 3D models natively, so developers can import glTF content directly and draw it through GLTiny APIs. Supported features include:
- lighting models
- skeletal skinning
- morph targets
- full glTF animation, including flexible playback, switching between animation clips and playback speed control
The model also supports Gaussian blur and ripple effects through simplified APIs.
Hybrid driver with VGLite renders 2.5D vector graphics and 3D models in one frame
GLTiny can be combined with VeriSilicon's VGLite vector graphics driver. The resulting hybrid driver coordinates 2.5D vector graphics and 3D models within the same frame.
"Power consumption and memory footprint are two of the most critical considerations in wearable devices," said Weijin Dai, Chief Strategy Officer, Executive Vice President and General Manager of the IP Division at VeriSilicon. He said GLTiny was developed with leading wearable SoC and device manufacturers. Dai described VGLite, VeriSilicon's 2.5D GPU programming model, as a de facto industry standard for lightweight 2.5D graphics. He added that GLTiny is designed to integrate with the established wearable graphics content development ecosystem.
