Hi all. First to thank for the great support you allways have provided me. I have modified the SelectionBox and SelectionHelper modules published in threejs in order to work with instances. The point is that if I try to use it with an orthographic camera the selection is not accurate. It works pr…

Hi. Not yet. I am still fighting with this issue. Best regards

Hi, i solved my problem. Maybe this solution helps you too raycaster.ray.origin.set( raymouse.x, raymouse.y, - 1 ).unproject( cameraOrtho ); but i used GPU Picker library

could you share a working example? In fact I am also using my own gpu picking. and tried unproject without accurate result

you can see the source code of my project. To switch the orthographic camera, please press “O” https://alovert.ru

Hi. The problem is not the same. I am trying to create a frustum from an area selection, not just gpu picking. By the way, I recommend you to depvelop your own GPU picking instead using gpuPicker. It is really simple do it by programming a shader. Another, thing, I also recommend you using insta…

Thanks for the advice! I am new to programming, and I study the library of three js for the third week. I never worked with shaders, tried to copy the code from the examples, but quickly got confused and refused this idea. Could you give me some example code, how can I add objects through instances…

There are two different ways to face the problem of dynamic adding | removing instances from the scene. The easiest way is to set a hard limit of instances for example (100000) for each asset you will have in your scene. You can control the current instances available in the scene by changing max…
