# Mesh deformation

Reshape and animate the geometry of 3D models at runtime, applying skinning, blend shapes, and subdivision so surfaces bend, flex, and deform as a scene plays.

## Overview

Overview This collection covers the building blocks for modifying the vertices of a model after it loads, letting you drive lifelike motion such as characters bending, faces emoting, or surfaces smoothing in real time. It includes a configurable pipeline of stages that transform geometry, options for choosing where and how that work runs on the processor or graphics hardware, and lower-level entry points for fine-grained control over the transformation. Reach for these tools when prebaked animation is not enough and you need to compute or adjust a model’s shape dynamically. They give you control over performance trade-offs and the order in which transformations apply.
