This is the result of this tutorial:
The example is simple and use two ways to draw text.
First use a function how make the text by using index variable to put on canvas same text.
The next use function strokeText to add to canvas the text.
The onload function is used to put on canvas all you need to see.
This is the source code for java script I used into head HTML5 tag :
window.onload = function(){
var canvas = document.getElementById("3dCanvas");
var canvasWidth = canvas.width;
var canvasHeight = canvas.height;
var ctx = canvas.getContext("2d");
ctx.font = "20pt Verdana";
ctx.fillStyle = "black";
ctx.textAlign = "center";
// first
drawTextInCanvas(ctx , "graphic-3d.blogspot.com", canvasWidth/2, canvasHeight/2, 4);
// the next
ctx.strokeText('... read this website !', 150, 150);
};
function drawTextInCanvas(ctx, mytext, wdth, hght, dpth){
var index;
for (index = 0; index < dpth; index++) {
ctx.fillText(mytext, wdth - index, hght - index);
}
// shadow casting in bottom layers
ctx.fillStyle = "#30F30F";
ctx.shadowColor = "black";
ctx.shadowBlur = 6;
ctx.shadowOffsetX = dpth+ 2;
ctx.shadowOffsetY = dpth+ 2;
ctx.fillText(mytext, wdth - index, hght - index);
}
Then add the canvas tag into body tag with this :
id="3dCanvas" width="400" height="200" style="border:1px solid black;"

Website tool for chemical data and infos.
Another website tool for chemical graphics and cheminformatics library.
The development team tell us:
The ChemDoodle Web Components library is a pure Javascript chemical graphics and cheminformatics library derived from the ChemDoodle® application and produced by iChemLabs. ChemDoodle Web Components allow the wielder to present publication quality 2D and 3D graphics and animations for chemical structures, reactions and spectra. Beyond graphics, this tool provides a framework for user interaction to create dynamic applications through web browsers, desktop platforms and mobile devices such as the iPhone, iPad and Android devices. This library also has complete access to the entire ChemDoodle desktop API through AJAX, allowing for quick access to one of the most robust chemical graphics and informatics packages in existence directly through Javascript. The goal of the project is to utilize the next-generation HTML5 technologies to power the scientific and educational applications of the future. iChemLabs is dedicated to funding, developing and hosting this library and has released it for free under the open-source GPL license. By releasing ChemDoodle Web Components open-source, yet continuing to financially support the library, iChemLabs ensures that the next generation of scientific applications is easily achievable by academia, government and industry, and helps to make sure that the cost of education decreases while using the web to further spread science.
This tool can be found on this website.
