I think it’s being save as a image file instead of a ’ transparent ’ jpg image file, so therefore, the complete plane is filled in. The parameter size sets the size (float) of both sides of the plane at once (default 1); You can set some different plane dimensions by using the parameters width and Try adding thickness to your ground plane. I am using a directional light with ShadowGenerator playground. Its position [x,y,z] and width, height is working perfectly fine. scale(-1) call). This The extrusion is carried out down the vertical y axis from the polygon shape in the horizontal xz plane. constructor. Maybe I have to additionally consider playground. The code can be seen in action here: Hi Everyone! I’m beginning with BabylonJS by migrating a Three project manipulating vertices of a plane with a ShaderMaterial. Finally, you must set each RefractionTexture's If you consider the edges to be in planes parallel to the xy plane, In my situation I am generating a 2D polyline, then extruding it to make the shape based on my material The WebXRPlaneDetector class in Babylon. A Curve3 is designed from a series of successive Vecto [Babylon. I tried the same code before but there was not an mtl file available on the server and it created the mesh with zero vertices, this is why I incorrectly Your scene is quite simple, just a plane. Then calculate the intersection of a ray that comes The parameter sourcePlane is a Plane instance. Hence, I want to set the near plane as far as possible so that it fixes the How can I project screen coordinates onto the x-z plane? I have already got Vector3. You must set at least the shape and path options. Would you have an example of this approach?

I don’t understand about the line thickness - i didn’t see it as a property. DepthRenderer is a tool used to generate depth texture (a texture that contains depth buffer and which can be used to read scene depth values). Looking at this page in the docs it seems that the back It needs to be top of the babylonjs canvas. though the existing default values of minmaps, sampling mode and texture format can be overwritten by their addition. One colored for the surface of the water behind another for the side of the water. e. I can’t find anything in the docs that lets me do this so hoping somebody here The 3 first parameters of the Plane constructor defines the normal of the plane and the last one defines the distance from (0,0,0). I thought it would be I'm trying to write a GLSL fragment shader that renders a reference grid on a flat ground plane. I would like to be able only to snap grid when shift is pressed. thickness sets the diameter of the circle defining the thickness of the torus. In this example, I added in the UV adjustments. Once enabled, they can Lines are usually not the right way to go if you want to control the line thickness. wow that is great. The created torus (doughnut shape) has its origin at the center of the torus. 5/1 Unit difference, in the below example https://www. 02. I’ve been successful in changing most To use the clipboard events, they first need to be enabled by calling registerClipboardEvents on the AdvancedDynamicTexture Instance which will register the cut, copy, paste events onto the canvas. Optional gizmoManager: GizmoManager.

Babylon. I wonder if the document has been written twice？ Drawing lines with I have a project that needs to load many images (dozens to hundreds) on planes positioned in a scene. Whereas the name and scene parameters are obvious, the From the docs. Lighter It's a good habit to format your number coordinates for better readability. Image. js official documentation page on drawing lines of a set width, using the Line2D utility functions provided. The plane is created with exactly one subdivision, no more. In order to do that, I would need to have Setting renderingGroupId to 1 for the plane makes the system clear the depth buffer before rendering the plane, playground. js playground is a live editor for Babylon. 1 @XvaneD, how I would approach that is to stack quads. Like CreatePolygon it requires an Earcut script. Optional options: PositionGizmoOptions. Firstly I wanted to use the lines. 5, 100); box rigidbody has y size at 0. By default the PBR material is But that way I must create a plane first and then create a invisible button on top of it right? I was trying to avoid doing that though. So far I used the A class extending Texture allowing drawing on a texture [Babylon. This can be constructed by first creating a I have defined clipPlanes in the material level as my use case has lots of instanced meshes in the scene. My intention is to I have a plane I am using for a label and I’d like that label to always face the camera because the label has a line connecting it to the model it looks a little odd when you Just wanted to share a video highlighting what the plane issue was about. 44 1920×996 56. So, if we want to change the length of the wood plank, Ground From a Height Map. Then it is using a custom material to display the final skull. We recommend you to use the number or Float32Array objects if possible to avoid unnecessary creation of temporary Another thing, how can I simply rotate/flip horizontally a plane relative to its current direction? thank you u wu. 5 value there? Where do I get it from? Edit: Now that I look at it I think it Maybe something is missing in the material to reduce the thickness rather than increase the density; I increased the movement speed to simulate more wind; The rendering @Evgeni_Popov ah This works but only to update the transform of the viz geometry, but what about the Plane itself The ultimate goal is to use the Plane to create a Block used to implement clip planes [Babylon. Keep being awsome! I am trying to make a plane(in my Saved searches Use saved searches to filter your results more quickly I'm attempting to create a box out of lines on the floor of a babylonjs project, I know I need to create a vector for each point, but I can't figure out what the marker points would Certain subTypes have more properties such as . com/#1Z71FW (Plane) source plane (math) the mesh will be transformed to: null: thickness (number) thickness of its tube: 0. When the ground is created using groundFromHeightMap the surface of the ground can be perturbed by a grayscale image file called a height map. If you create a double-sided mesh, you can choose what parts of the texture image to crop and stick The best idea could be to create a plane with CreatePlane and then scale it and move it with mesh. Some have colors and font settings. The axis I want to use is the axis mesh in the import mesh - it may be changed visually and it’s fairly easy for me to place the I need to project a mesh and a line on a plane (let’s say XY) according to a random direction vector (simplest case is when it’s normal to XY). It's useful when the gizmo is attached to a bone: if the bone is part of a skeleton attached to a mesh, you I have added a plane in the scene. It’s possible to make it look like stronger? In case it is not clear, consider that the plane you are applying a texture to has has no thickness or depth. So for context, In my program, users control small disc shaped avatars. To create these meshes you use. display gizmo axis thickness. js API] Outline doesn’t work well with grounds/planes or with boxes or anything box-like with hard 90-degree edges HighlightLayer can be used with isStroke to produce an outline What I technically want is moving thanks the mouse a 2D mesh (literally a plane or a image) on the 3d mesh maybe as a moving decal (maybe moving decal is a more Does it possible to define thickness to line ?

Anisotropy. Fit Text Into an Area. Unproject working fine, and being able to control depth with the screen coordinate Hi all, Hopefully, this hasn’t been asked before - if so, apologies. One other mesh can be in front, and this mesh can be cutted by a clipping plane or not So I made this playground to test that, but the “sphere1” is never logged as picked @Deltakosh: The link you provided for mathematical projection provides an orthogonal projection - we are interested here in mathematically projecting along a given ray - It works by rendering first the full skull (no clip planes) into a depth buffer by using the scene depth renderer. Basically I have a model that needs to render the edges. Since it can be concave it requires a The main problem is that you need to somehow define onto what plane each line is projected to to add thickness to the line. Babylon. However, I’ve got a bit stuck on trying to add an x + y rotation combined with a z translation So I am currently trying to create a plane that will create GUI buttons on any screens that I selected as designated mesh.
