Dear All,
Below is the code listing to try out the dynamic texture on imported mesh, but kind of fail on the "targetMesh".
It only works when I'm using Plane mesh "newPlane" produced from the code using BABYLON.Mesh.CreatePlane.
Am I missing something here?
BABYLON.SceneLoader.Load("", "plane.babylon", engine, function (newScene) {
newScene.executeWhenReady(function () {
var canvas = engine.getRenderingCanvas();
//newScene.activeCamera.attachControl(canvas);
// This creates and positions a free camera (non-mesh)
var camera = new BABYLON.FreeCamera("camera1", new BABYLON.Vector3(0, 5, -125), newScene);
camera.setTarget(BABYLON.Vector3.Zero());
camera.attachControl(canvas, true);
newScene.activeCamera = camera;
//now here I want to select some meshes from the active scene
var targetMesh = newScene.getMeshByName('plane');
if(targetMesh) {
// debugger;
// Create new standard material
var stdMat = new BABYLON.StandardMaterial('Material', newScene);
stdMat.alpha = 1;
stdMat.backFaceCulling = true;
stdMat.specularPower = 64;
stdMat.useSpecularOverAlpha = true;
stdMat.useAlphaFromDiffuseTexture = false;
// emissive definitions;
stdMat.emissiveColor = new BABYLON.Color3(0.00, 0.00, 0.00);
// ambient definitions;
stdMat.ambientColor = new BABYLON.Color3(0.00, 0.00, 0.00);
// specular definitions;
stdMat.specularColor = new BABYLON.Color3(1.00, 1.00, 1.00);
var dynTexture = new BABYLON.DynamicTexture("Dynamic texture", 1024, newScene, true);
dynTexture.uScale = 1;
dynTexture.vScale = 1;
dynTexture.coordinatesMode = 0;
dynTexture.uOffset = 0;
dynTexture.vOffset = 0;
dynTexture.uAng = 0;
dynTexture.vAng = 0;
dynTexture.level = 1;
dynTexture.coordinatesIndex = 0;
dynTexture.hasAlpha = false;
dynTexture.getAlphaFromRGB = false;
// set stdMat diffuse texture
stdMat.diffuseTexture = dynTexture;
// draw text
dynTexture.drawText("Eternalcoding", null, 100, "70px Segoe UI", "red", "#555555");
// set sub mesh material
targetMesh.material = stdMat;
// calculate mesh size
var vectorsWorld = targetMesh.getBoundingInfo().boundingBox.vectorsWorld;
var size = vectorsWorld[1].subtract(vectorsWorld[0]).length(); // distance between summit 0 and summit 1
// New Plane
var newPlane = BABYLON.Mesh.CreatePlane("New Plane", size, newScene, false);
newPlane.scale = 0.5;
newPlane.position.z = targetMesh.position.z;
newPlane.position.y = targetMesh.position.y;
newPlane.position.x = targetMesh.position.x+(size/2);
// newPlane.parent = targetMesh;
// set sub mesh material
newPlane.material = stdMat;
stdMat.diffuseTexture.update();
}
engine.runRenderLoop(function() {
newScene.render();
});
});
});
Here is the "plane.babylon"

I had to travel to Thailand (my Wife is Thai) for personal family issues which will take me back to Thailand on the 24th. So I had to put my multiuser real time drawing app on hold. But now I want to complete the first version in the next week, and am really stuck on something today.
