Learning WebGL 3D: Starting Textures and Lights

On 01, Jun 2016 | 11 Comments | In 3D, JavaScript, Learning, WebGL | By synergyseeker

We’ve already covered the basics of setting up a scene, a camera, the render loop ( animation loop ) and some other basics about geometry and transformations in previous tutorials. In this lesson, let’s dig into applying textures and materials to “skin” our objects and adding lights, so we can see them. Read more…

Learning WebGL 3D: Transformations – Rotation, Scale, Translation

On 20, Mar 2016 | 18 Comments | In 3D, JavaScript, Learning, WebGL | By synergyseeker

So in the first lesson, you learned about setting up the files, getting set up with a 3D helper library and doing your first render. In fact we jumped ahead in that first lesson and did a simple rotation, which is the first of our transformations we are going to look at.

Learning WebGL 3D: Getting Started with ThreeJS

On 07, Mar 2016 | 30 Comments | In 3D, HTML5, JavaScript, Learning, News, WebGL | By synergyseeker

WebGL, is a JavaScript API for creating and rendering graphics inside an HTML <canvas> element. We already used this element in previous lessons here, and the same basic concepts can be applied. In a basic sense, we are still using math to draw frames that we cycle through at high rates ( 60fps ) to create the optical illusion of motion.

Javascript Animations: Lesson 8 – Acceleration and Gravity!

On 08, Feb 2016 | 8 Comments | In General, HTML5, JavaScript, Learning, Prototypes | By synergyseeker

 

Acceleration! The change of velocity over time. So, if velocity is the change of speed over time, this is the change of that velocity over time. This could be changing direction, speeding up or slowing down. Really it is just another vector applied to another over time. Because it is continually added it increases the magnitude of the that initial vector over time.

Javascript: Random Spheres Trig

On 05, Feb 2016 | 13 Comments | In 3D, General, HTML5, JavaScript, Learning, Prototypes, The Lab, WebGL | By synergyseeker

If you have been following along with the Learning tutorials so far, you’ll recognize the basis of experiment comes from Lesson 5 – Making multiple objects move  In this demo, I am using radial gradient fills, a range of colors, and some good ole fashion trigonometry to create a nice 3D  effect.

Javascript Animations: Lesson 7.5 – Vectors as forces to move player

On 02, Feb 2016 | 7 Comments | In Games, HTML5, JavaScript, Learning, Prototypes | By synergyseeker

Ok so we are making a game. Well not really a game, but if we were, we might need a  player object. So we have a player object a really awesome cool triangle. Lame, I know, but actually I loved asteroids and well the little dude was just a triangle. So we have a trianlge and we are going to make it rotate and move around using our learnings from previous lessons. So if you are totally lost jump back and read on Vectors and if you are really, really lost jump back and read from the start about animations.

Javascript Animations: Lesson 7 – Vectors

On 29, Jan 2016 | 10 Comments | In Games, HTML5, JavaScript, Learning, Prototypes, WebGL | By synergyseeker

Vectors. Yep Vectors. So what is a vector? A vector is a magnitude ( a number ) and a direction. These 2 elements are a vector. So speed is not a vector, because it is just a magnitude, but velocity is a vector because it tells how fast and in what direction something is going.

Javascript Animations: Lesson 6 – ArcTangent to find angles

On 25, Jan 2016 | 6 Comments | In HTML5, JavaScript, Learning, Prototypes | By synergyseeker

Screen Shot 2014-02-28 at 5.30.09 PMOk, so let’s say we have a video game and your character runs around.  The bad guys tend to follow you and look towards where you are. Let’s make a simple demo to illustrate this. We are going to make a triangle bad guy that flies around. He points where the mouse is on the screen.

If you recall the TAN is the opp/adj of an angle. The inverse TAN is the inverse of this value. So if we have a point at the origin and another at a distance ( x, y) from that origin. We can break the x,y into component lengths of x being the adj and the y being the opp.

Javascript Animations: Lesson 5 – Moving multiple objects

On 21, Jan 2016 | 2 Comments | In HTML5, JavaScript, Learning, Prototypes | By synergyseeker

Moving multiple objects is a bit misleading, if you have been reading along to this point. As you might recall from lesson 1, we are actually drawing a new image on the screen each frame , and not actually “moving” anything. However we create this illusion of motion by moving or changing things 1 frame at a time. Once we code our animation the result is motion.
