## Key takeaways

- VeriSilicon announced GLTiny, a 3D GPU programming model with a simplified API and ultra-light driver for smartwatches, smart glasses and other resource-constrained wearables.
- GLTiny supports native glTF rendering, skeletal meshes, morph targets and animation clips, and can pair with VeriSilicon's VGLite driver for hybrid 2.5D and 3D rendering.
- Weijin Dai, VeriSilicon's chief strategy officer and general manager of the IP division, said power consumption and memory footprint are two of the most critical considerations for wearables.

VeriSilicon announced GLTiny, a 3D GPU programming model for wearables with strict power and memory limits, on October 29, 2026. The Shanghai company said the model pairs a simplified API with an ultra-light driver and runs on its Nano OpenGL ES GPU IP family for smartwatches, smart glasses and other resource-constrained devices, according to [PR Newswire](https://www.prnewswire.com/news-releases/verisilicon-presente-gltiny-un-modele-de-programmation-gpu-3d-pour-les-appareils-portables-ultra-basse-consommation-et-a-faible-consommation-de-memoire-302922517.html).

## How GLTiny Handles 3D On Wearables

[VeriSilicon Holdings](https://akta.pro/company-profiles/0007yty/verisilicon-holdings) said GLTiny includes configurable rendering functions that let developers set their rendering requirements while using the underlying OpenGL ES GPU capabilities. The company said this approach reduces the driver's memory footprint and CPU load, improving energy efficiency for wearables.

GLTiny offers native rendering support for standard glTF 3D models, so developers can import glTF content directly and render it through GLTiny APIs. The model supports lighting models, skeletal meshing and morph targets, along with full glTF animation support including flexible playback, switching between animation clips and playback speed control. GLTiny also supports visual effects such as Gaussian blur and ripple effects through simplified APIs.

GLTiny can be combined with VeriSilicon's VGLite vector graphics driver to form a hybrid driver that renders 2.5D vector graphics and 3D models together in the same image. Weijin Dai, chief strategy officer, executive vice president and general manager of the IP division at VeriSilicon, said: "Power consumption and memory footprint are two of the most critical considerations for wearables, where delivering rich visual experiences under highly constrained resources is essential." Dai said GLTiny builds on the VGLite 2.5D GPU programming model and works across VeriSilicon's Nano OpenGL ES GPU IP range.

## VeriSilicon's Wearable Graphics Record

VeriSilicon closed its acquisition of Pixelworks Semiconductor Technology (Shanghai) Co., Ltd. for approximately $51 million in January 2026, adding Pixelworks' semiconductor design capabilities to its portfolio, according to akta.pro [company records](https://akta.pro/company-data). In November 2025 the company jointly launched the open-source Coral NPU IP with Google, based on the RISC-V ISA, for always-on ultra-low-power edge AI applications in wearables and IoT.

## Earlier Wearable And GPU Partnerships

In July 2026, VeriSilicon partnered with LVGL to integrate its low-power 3D and VGLite 2.5D GPU technology into the LVGL graphics library, with Actions Technology among the first to adopt the solution in its smart watch SoCs, AETOSWire reported. That same month, QDay Technology joined VeriSilicon's watch GUI ecosystem to develop smart watch GUI solutions, AETOSWire reported. Also in July 2026, HPMicro's HPM6800 series RISC-V MCU platform adopted VeriSilicon's 2.5D GPU IP for dashboard and HMI applications, AETOSWire reported.
