In computer vision, the transformation from 3D world coordinates to pixel coordinates is often represented by a 3x4 (3 rows by 4 cols) matrix P as detailed below. Given a camera in Blender, I need ...

I have a script whose goal is to find all the visible vertices from the camera view. The simplest solution should work as follows: Go Into Camera View Update the view with ...

In Blender2.74, I want to circle-select the vertices in the "3D View", using this: circle_select(x = 300, y = 400, radius = 30). I found this question. So I know ...

Here is my target application. The rendered image with rendered meshes is used in an interactive application. A user may click or point the cursor to an object on the image. Information related to ...

Suppose I have the following camera perspective. As you can see some of the Cube vertices are visible from the camera, others are not. Is there a way from python to detect if a certain vertex is in ...

I can obtain the coordinate of a mesh vertex with python via wco = mesh.vertices[mesh_vert_idx].co Further, it is possible to convert this coordinate system to ...

In computer vision, the transformation from 3D world coordinates to pixel coordinates is often represented by a 3x4 (3 rows by 4 cols) matrix P as detailed below. Given P I need code to return a ...

I would like to obtain the pixel coordinates of an object's outline in the currently-rendered scene, using the bpy module. I found this, which is related, but I'm still not sure how to do it. Has ...

I wanted to know if anyone had to find a object by only knowing the pixel (x: 300, y: 300)information in a final render say like (essentially using camera view) Is there a way to find the correct ...

I can use the recipes on this page: How to find image coordinates of the rendered vertex?. But is there a way to know if a point is being occluded by some point/face in front of it from the viewpoint ...

I am trying to get the pixel coordinates of the object in the rendered image in blender using the How to find image coordinates of the rendered vertex? But I get the error AttributeError: 'Mesh' ...

What I want to do I want to change the power of only the light object visible in the camera view. I want to remove vertices to mesh objects in visible in the camera view. Not remove mesh objects, ...

I am using Templates->Python->Operator Modal View3D Raycast template script which uses event.mouse_region_x, event.mouse_region_y to create raycasts into the ...

The bgl module allows us to obtain various information displayed in 3D Blender view. For example, I made a script that gets the 3D coordinate where the mouse cursor hits a object: ...

For a research project I am using Blender's Python API to generate some simple random scenes. In addition to the generated renders, I need to acquire a 'foreground mask' in screen (image) coordinates ...
