After browsing the samples on http://threejs.org, I couldn't find any information about hit detection for ColladaLoader objects. The examples mainly focus on basic mesh shapes.
Is it feasible to perform hit detection on Collada objects? If yes, how would the syntax be structured?
Take a look at this website to see if it fits your needs.
It appears to align with what you are seeking.
For information on Collada objects detected using THREE.JS RAY CASTER, check out this useful link. You may need to adjust the Ray Class for compatibility.
Here are some resources I've come across regarding the concept of selecting objects using mouse in THREE.JS. Some of the initial links may be outdated, but they still provide valuable insights.
Jens Arps penned an insightful piece on this subject where he highlighted the necessity of a custom THREE.Raycaster for detecting Collada Objects.
However, post THREE.JS r62, this approach is no longer mandatory. Mouse picking can now be achieved with a Raycaster, Projector, and Vector3. If you refer to Jens Arps's latest publication, you will find a detailed guide on the steps required. Although slightly challenging initially, especially with the inclusion of a FirstPersonControls camera, eventually everything falls into place.
By studying the provided code, I managed to select and interact with various Collada Objects.
ColladaLoader along with other loaders can import objects from distinct formats into a standard THREE.Mesh
As a result, there is no requirement for unique code for collision detection on a collada-imported mesh.
This also signifies that if your code functions with a collada-imported mesh, it will function with any alternative source format as well.
