What is point cloud in Nuke?

Using the PointCloudGenerator node (NukeX and Nuke Studio only) you can create a dense point cloud based on the information generated by CameraTracker and use the dense point cloud further to create 3D meshes of your 2D footage. Note: The analysis must be performed in NukeX, but the result can be used in Nuke.

What can point clouds be used for?

Point cloud data is used around the globe in a variety of industries, from construction and engineering to highway planning and the development of self-driving cars. Point clouds allow technology to interpret and represent 3D spaces through 3D digital images.

What is point cloud format?

A point cloud is a set of data points in space. The points may represent a 3D shape or object. Each point position has its set of Cartesian coordinates (X, Y, Z). Point clouds are generally produced by 3D scanners or by photogrammetry software, which measure many points on the external surfaces of objects around them.

What is compositing in Nuke?

3D Compositing teaches you how to create and manipulate 3D scenes composed of objects, materials, lights, and cameras. Stereoscopic Scripts describes how to composite stereoscopic material in Nuke. Deep Compositing goes through using the deep compositing node set in Nuke.

What is mask in nuke?

An extremely powerful feature of NUKE is being able to mask almost any node by the mask input on the side. This video shows the power and steps to use this crucial feature.

How is a point cloud created?

Point clouds are created by performing a scan of an object or structure. Scans are completed by using either a laser scanner or through a process called photogrammetry.

How big is a point cloud file?

Depending on the nature of the project, that is likely somewhere between 5mm and 25mm between data points.

How do I create a point cloud file?

Help

1. Attach one or more RCS point cloud scans or RCP point cloud projects to the drawing.
2. Click Home tab Create Ground Data panel Surfaces drop-down Create Surface From Point Cloud Find.
3. Select a point cloud, or use one of the command line selection options to select an area of one or more point clouds.

How to create a dense point cloud in Nuke studio?

Using the PointCloudGenerator node ( NukeX and Nuke Studio only) you can create a dense point cloud based on the information generated by CameraTracker and use the dense point cloud further to create 3D meshes of your 2D footage. Dense point clouds are a useful starting point for 3D modeling and positioning objects in a scene.

How to get position to points in Nuke taukeke?

Surface Point: This is where you choose the Position pass render. As you copy the channel, make sure to label the Red, Green and Blue channels as X, Y and Z respectively. Surface Normal: This is where you choose the Normal pass render. Same procedure as usual as mentioned above.

Do you need normal pass for position in Nuke?

You need a Position pass and Normal pass from your 3D renderer. Ensure it is both in 32-bit floating point (EXR is your best format) and in world-space. Verify that it is NOT CLAMP. For this example, I did a mistake when outputting from Octane Render with the tone mapping enabled (even though it is set to Linear response).

How to increase the size of a point in Nuke?

Point Detail: Adjust the amount of points being rendered in the 3D space. Lower down the value if Nuke struggle to navigate the 3D space if the point cloud is very dense. Point Size: Adjust the size of the point. Increase it if you need to see the point bigger and vice versa.
