||
| A contact shadow implementation is a technique used in 3D graphics to create shadows that appear where objects meet or "contact" each other. This is different from traditional shadowing techniques, which often only create shadows based on the position of a light source relative to an object. | ||
|
|
||
| This component is used to create and manage contact shadows in a 3D scene. It is based on the original code by [@mrdoob](https://twitter.com/mrdoob) and the implementation in [pmndrs drei](https://github.com/pmndrs/drei/blob/master/src/core/ContactShadows.tsx#L113) but adapted for Vue Composition API. | ||
| `<ContactShadows />` is a "fake", non-lighting-based shadow component. It displays shadows on a single plane. The component is based on the [THREE.js contact shadows example](https://threejs.org/examples/webgl_shadow_contact.html) by [@mrdoob](https://twitter.com/mrdoob). | ||

||
| ## Usage | ||
|
|
||
| ```vue{11} | ||
| <template> | ||
| <TresCanvas v-bind="gl"> | ||
| <TresPerspectiveCamera :position="[11, 11, 11]" /> | ||
| <OrbitControls /> | ||
| <Box ref="boxRef" :args="[0.4, 0.4, 0.4]" :position="[0, 1, 0]"> | ||
| <TresMeshNormalMaterial /> | ||
| </Box> | ||
| <Icosahedron ref="icoRef" :args="[0.3]" :position="[1, 1, 1]"> | ||
| <TresMeshNormalMaterial /> | ||
| </Icosahedron> | ||
| <ContactShadows :blur="0.5" :resolution="512" :opacity="0.2" /> | ||
| <Plane :args="[10, 10, 10]" :position="[0, -0.02, 0]"> | ||
| <TresMeshBasicMaterial :color="'#ffffff'" /> | ||
| </Plane> | ||
| <TresAmbientLight :intensity="1" /> | ||
| </TresCanvas> | ||
| </template> | ||
| ``` | ||
