This can be useful if you’ve made changes to a particular object and want to see how those changes have affected it without having to render the entire scene. Instead, you can place a clipping sphere around the object and render only that part. This is similar to doing a cropped render in 2D. In the rendered image, everything outside of the clipping sphere is not visible, giving the impression that the object is isolated in space. In some cases, you might want to do the opposite and render everything outside of the sphere, creating a hole in the final render. This technique can also be used for animations where a large part of the scene is static and unaffected by the animation (such as shadows and reflections). By rendering this static part of the scene once using the clipping sphere feature, usually outside the sphere, you can save time and resources during the animation rendering process, by just rendering inside the sphere for the animation. ![](/files/d3HmxaQ6hRy76Pjkrc7T) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.v-nova.com/technologies/v-nova.presenz/v-nova-presenz-documentation/the-clipping-sphere.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
