Hey I have 2 questions and I hope someone can help me!

Is there a way to draw lines from the curser inside the 3D space? Like drawing free lines inside the scene in the application.

Is it possible to use an image/video for light projection? Kind of like a beamer/projector? Is it supported by verge3d?

Thank you for any help!

Drawing lines… it depends on what you really mean. You can create drawing tools over the canvas. But if want to show a line from the pointer to an object in 3d space … it’s possible but like draw tool … not pretty.

Light projection is not supported. However there are lots of things you can do to fake it if your scene supports it creatively.

Possible. Just provide two points in the 3D space (you wil have to use a raycaster for that purpose) and this puzzles will draw a line.

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

Okay thank you! I meant drawing free lines, not straight but like drawing with a pen into 3d space.

Ok. In this case the answer is short and simple: No.

I was also searching for any possibility to show the line getting drawn in 3D space with controlled animation speed. The progressing line…it may have turn & loops !

As Alissa saying,
I feel there two wats mainly
A) One the user facility to draw from point A to B
B) Second is animated line getting drawn from point A to B

Intention for B is to use in schematic diagrams to show the flow

It’s quite possible to draw lines on meshes with UVs

Canvas Plugin for Verge3D – Creating Canvas Texture No Code

but hardly possible to do it in the pure 3D space. coordinates will be undefined.
