Transform Controls

The Transform Controls are a set of three gizmos that can be used to translate, rotate and scale objects in the scene. It adapts a similar interaction model of DCC tools like Blender

Usage

To use the Transform Controls, simply add the TransformControls component to your scene. You can pass the templateRefof the instance you want to control as a prop.

<script setup>
const boxRef = shallowRef()
</script>
<template>
  <TresCanvas>
    <OrbitControls make-default />
    <TresScene>
        <TransformControls :object="boxRef" />
        <TresMesh ref="boxRef" :position="[0, 4, 0]" cast-shadow>
            <TresBoxGeometry :args="[1.5, 1.5, 1.5]" />
            <TresMeshToonMaterial color="#4F4F4F" />
        </TresMesh>
    </TresScene>
  </TresCanvas>
</template>

::: warning If you are using other controls (OrbitControls) they will interfere with each other when dragging. To avoid this, you can set the makeDefault prop to true on the OrbitControls. :::

Modes

The Transform Controls can be used in three different modes:

Translate

The default mode allows you to move the object around the scene.

<TransformControls mode="translate" :object="sphereRef" />

Rotate

The rotate mode allows you to rotate the object around the scene.

<TransformControls mode="rotate" :object="boxRef" />

Scale

The scale mode allows you to scale the object around the scene.

<TransformControls mode="scale" :object="sphereRef" />
