Exporting Three.js scene to STL keeping animations intact


Exporting Three.js scene to STL keeping animations intact

this will help
The question is where are these transformed vertices and faces stored and can I access them to export them as an STL?
code :
vector.copy( vertices[ vertexIndex ] );
boneIndices = [];   //which bones we need
boneIndices[0] = mesh.geometry.skinIndices[vertexIndex].x;
boneIndices[1] = mesh.geometry.skinIndices[vertexIndex].y;
boneIndices[2] = mesh.geometry.skinIndices[vertexIndex].z;
boneIndices[3] = mesh.geometry.skinIndices[vertexIndex].w;

weights = [];   //some bones impact the vertex more than others
weights[0] = mesh.geometry.skinWeights[vertexIndex].x;
weights[1] = mesh.geometry.skinWeights[vertexIndex].y;
weights[2] = mesh.geometry.skinWeights[vertexIndex].z;
weights[3] = mesh.geometry.skinWeights[vertexIndex].w;

inverses = [];  //boneInverses are the transform from bind-pose to some "bone space"
inverses[0] = mesh.skeleton.boneInverses[ boneIndices[0] ];
inverses[1] = mesh.skeleton.boneInverses[ boneIndices[1] ];
inverses[2] = mesh.skeleton.boneInverses[ boneIndices[2] ];
inverses[3] = mesh.skeleton.boneInverses[ boneIndices[3] ];

skinMatrices = [];  //each bone's matrix world is the transform from "bone space" to the "global space"
skinMatrices[0] = mesh.skeleton.bones[ boneIndices[0] ].matrixWorld;
skinMatrices[1] = mesh.skeleton.bones[ boneIndices[1] ].matrixWorld;
skinMatrices[2] = mesh.skeleton.bones[ boneIndices[2] ].matrixWorld;
skinMatrices[3] = mesh.skeleton.bones[ boneIndices[3] ].matrixWorld;

var finalVector = new THREE.Vector4();
for(var k = 0; k<4; k++) {
    var tempVector = new THREE.Vector4(vector.x, vector.y, vector.z);
    //weight the transformation
    tempVector.multiplyScalar(weights[k]);
    //the inverse takes the vector into local bone space
    tempVector.applyMatrix4(inverses[k])
    //which is then transformed to the appropriate world space
    .applyMatrix4(skinMatrices[k]);
    finalVector.add(tempVector);
}

output += '\t\t\tvertex ' + finalVector.x + ' ' + finalVector.y + ' ' + finalVector.z + '\n';

How to selective redraw shapes keeping other intact

To fix this issue There are probably several things you can do to improve the behavior.
Override OnPaintBackground and leave it empty Cache that SolidBrush instead of creating a new one every time OnPaint is called Draw all of the shapes that are static to a member-level Bitmap that you cache. In OnPaint, do a DrawImage of that image then your arrowhead and line (the changing stuff). Do all of this drawing to a Bitmap (that you cache, not create every time), then DrawImage that to the screen graphics If you don't have overlapping stuff and you've got reasonable rectangular regions, setting a clipping area to surround your changes will prevent unnecessary drawing

Hope that helps After deleting an entry from a file, am left with a blank line where the entry used to be, and would like to know how to get rid of it at the same time of script execution. , Capture the line break in the regex:
code :
$bodycont = preg_replace("/\b({$_POST['inscripnum1']})\b\n/","",$index);

With these it helps You are considering adjusting your to-storage mechanism to make updates somewhat easier. The expense you incur is to make the consumer's life harder, they would need to fetch two properties.
Generally, I would favour making the consumer's life easier at the expense of making "plumbing" code more complex.

may help you . I have 5 web pages with different domain names. Each of them uses the same directory and the same .htaccess file. I've redirected non www urls to www with this lines: , Just target your rule for main domain:
code :
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$ [NC]
RewriteCond %{HTTPS}s on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
