QUESTION
I am new to three.js but I have past experience from Unity with 3d objects and rendering, I am having trouble with the SpotLight, I am trying to shed light from an imported obj, to make it seem like a working lamp. I can't set the light's angle to an acute one because it just doesn't illuminate when it is beyond a certain value.
this is the relevant code for this:
...ANSWER
Answered 2020-Dec-10 at 01:42I think it's because you're using MeshLambertMaterial, which calculates lighting on each vertex, instead of calculating on each face pixel. When the light hits a vertex (wide angle) it illuminates. But when the light only hits the face and doesn't touch a vertex (on narrower angles), the plane face doesn't show the light. Also, shining a yellow light on a blue box won't show anything due to the nature of light: #ffff00 * #0000ff = #000000.
Try changing to MeshPhongMaterial, and you'll see your lights and shadows being calculated more accurately. Run the code snippet below to see it in action.

QUESTION
How to make the plane draggable in X , Y direction. Here I'm trying to work on box clipping where I draw a plane on X and Y direction. But I have no idea how to make it draggable to the particular direction. Can anyone help me put with the issue.
I want to make the plane to be draggable only in the own direction on mouse event
...ANSWER
Answered 2020-Apr-24 at 13:55In order to move things in three.js you use TransformControls. Check out https://threejs.org/docs/#examples/en/controls/TransformControls for its documentation and https://github.com/mrdoob/three.js/blob/master/examples/misc_controls_transform.html for implementation example.
Here you can set the mode to "translate" and scale to "XY" to restrict the movement in X and Y direction only.
QUESTION
I'm creating an HTML file integrating ThreeJs, basically I have created 4 Spheres, 1 of them projects the light, other 3 spheres turn in a wall. When the Spheres is behind the wall they should not reflect the light, what I supposed to do to solve this?
I've already try changing the materials of the Spheres which turns around the wall to Lambert and Phong, setting up castShadow to true, and recieveShadow to False
...ANSWER
Answered 2019-Apr-18 at 08:46One way to achieve your intended result is to work with shadows. So you have to set Object3D.castShadow and Object3D.receiveShadow to true for your spheres and your ground like in the following live example:
https://jsfiddle.net/85q3sfeg/
Also keep in mind that three.js does not support selective lighting so far. This issue was already discussed at github right here: https://github.com/mrdoob/three.js/issues/5180
Assuming all objects of your scene have a lit material applied, you can't define what light sources should affect what objects.

QUESTION
I am trying to add a on click handler that will toggle the light attribute on an entity when a separate entity is clicked. However nothing is happening when I click the separate entity, and I have no errors in my console.
Here is my component:
...ANSWER
Answered 2018-Jan-21 at 13:26You can't have a uppercase letter in the component name, a-frame will try to make it lowercase, (...) in the end it won't work.
Try naming it lightsout or lights_out. Throw in a console.log() when clicked, to be sure it's properly working.
Also You need to refresh the raycaster manually, using raycaster.refreshObjects(), it's a bug, which is fixed by december 2017 in the master build.

Install Penumbra
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
