(3d object to json to webgl). Will I be able to manipulate skin of that 3d from webgl/javascript?
Yes, you will be able to manipulate the material. Take a look at: http://threejs.org/examples/#webgl_materials_cars As you can see, each car is a single object that also holds informations about which triangle that model is made of corresponds to which material that is exported. There are many different ways to control the apperiance of the object, but the answer remains the same - it is possible, it's up to you to decide how're you gonna do it. Hope this helps.

Use Canvas in SVG or WebGL for 3D application
HTML5 / Canvas / SVG are good for static images, but not for a 3D application that allow movement. I have tried some months ago to implement a stellar map with HTML5 and also tried with SVG, but all movement (to scroll the map or see another zone) are slow. Different browsers has also a huge impact: for example moving a big image or moving 100 objects has a very different result in efficiency in Chrome and Firefox. WebGl is a simplification of OpenGL for web, which use the graphic cards like a game and allow very complex 3D application. As an example, Command and conquer online, or http://www.unrealengine.com/html5/ use webGL. The problem of webGL is that it requires a compatible browser, and for example IE does not support it. If your application does not require to be very browser-comp

HTML5 textarea canvas webGL
In order to set the GLSL shader program you use, you always follow the same steps: create the pixel- or vertex shaders with context.createShader obtain the sourcecodes for the shaders set the sourcecodes for the shaders through context.shaderSource compile the shaders with context.compileShader create a new webgl program with context.createProgram attach the shaders to the program with context.attachShader link the shader with context.linkProgram tell the canvas to use the complete shader program with context.useProgram Details about these individual steps can be found in any of the countless WebGL tutorials you can google. The only thing you want to do differently is step 2 - how to obtain the sourcecodes of the pixel- and the vertex shader. Most tutorials store the GLSL sourcecode

Background (canvas) color disappears when rendering multi-mesh object in WebGL
There are two possibilities: the white is the default color of the canvas and it is still there because webGL context is not properly initialized. Check console, if there are some errors with init, than you found your porblem, if that's not the case then it's second option the white is drawn on canvas with no errors and that might happen if your shaders output the white fragments and you put too big objects, so you ended up looking at one side of the pyramid/cube and everything else is being blocked from the view because of that one side. Looking forward to feedback.

wrap text and center align in javascript function by appending & prepending spaces

Server side javascript with WebGL?
I am new to WebGL as well, but I still feel that this is a very advanced question you are asking. I believe it is an advanced question because of the scope of answers that exist to do what you are asking and the current problems related to proprietary WebGL. If you have done any research into WebGL you will immediately see the need for Server Side code due to the fact that the WEbGL API code is executed within the browser and thus freely available to any knowing individual. This is not a typical circumstance for game developers who are used to shipping their code compiled. By making use of server side controls a developer can hide a large amount of WebGL translations, shaders, and matrices, and still maintain a level of information hiding on the client side code. However, the game will

How to align children items in canvas to print with gridspan
Setting Grid.SetRow and Grid.SetColumn attached properties works only if specified object is wrapped in Grid. In your case your mainCanvas1 and mainCanvas are wrappep in mainCavasFinal. So only mainCavasFinal is affected by Grid attached properties. If you want to use Canvas container you can manage its children position using Canvas methods: Canvas.SetLeft(mainCanvas, 100); Canvas.SetTop(mainCanvas, 100); or you can pring Grid itself, see: Print Grid which generated dynamically in wpf

Adding "new line"s to text in text supporting objects (i.e Buttons, Rich Text boxs) both in and out of code
" " is the escaped character for a line break. So code like: label.Text = "This is a button"; Should put the word button on a new line. Edit: If you want to do it using the properties window in designer, click on the arrow on the far right of the text property field and it will open a small box. If you type multiple lines on that as you would normally (ie actually pressing enter, not using ) then the component will treat them as new lines and put the new lines in for you.

WPF C# Canvas Drawing Line connecting buttons
Whilst you can do it by moving the Canvas around, you might be better off using the positions of the Buttons themselves on the Canvas. Essentially, you need to have two sets of coordinates, your LineStart and LineEnd, which in this case will be obtained from the two different Buttons you're clicking. You could use Point location = ((Button)source).TransformToAncestor(Canvas1).Transform(new Point(0, 0)) to obtain the location of the button being clicked, relative to the parent Canvas. You would then need to do a similar thing to find the location of the original object that you had clicked (which you don't seem to be storing). You could then simply draw a line between the two calculated Points by setting the X1, X2, Y1, Y2 values. Adapting your example, you could do something like this

SKIA :: Get Text height of a text inside a canvas
I once had to look into this myself in the past, this link here should help you, even though it is java, fonts all work on the same idea as far as I know. I assume you will want from the ascender to the baseline, Which is just the ascent. Or you may want the whole thing from top to bottom which is the ascent and descent combined, If you were writing on lined paper, the baseline is the same as the line you write on, anything above that is the ascent, anything below is the descent. I dont know anything about skia, But A quick look into skia, at this link here, that there is a public member called fAscent in FontMetrics, and fDescent, Maybe you can use those.
