Some are just “parasites”, existing only by stepping over other people work. Those events really confirmed to me that there are 2 kind of people. The other side of is the fact that this animation has been stolen without credit a hundred times and some of them put their name over mine. Of course I’m not categorical but create for myself is more important than any collaboration. It’s not about selfishness, I just like to keep creativity intimate. However, for me the most important is the fact that they notice my work rather than the things it could bring. So it had an interesting impact for sure, and still today. (My favourite was maybe when the director of District 9 movie, Neil Blomkamp wrote on Instagram to congratulate me and told me that he loves my work). People from different domains contacted me, directors, singers, producers. The building used for this animation is located in Auray, in the Morbihan region of France. It took me some time to accept that the final render was not so bad. The funny thing is that I was close to gave up this project because I had some physics issues, that’s why some part are cut, and showing them would have ruin the scene. It wasn’t expected and that was a very cool surprise. I’ve built a simple helper function which adds the plane to the container layer directly and then returns the new plane layer.Were you prepared to the huge success that followed the publication of this insane video? Then we create another CALayer to represent a plane. With this function we are going to draw a plan rotated by 45 degrees on the Y axis.įirst, we create a CALayer that we use as container (it is not required, but I prefer not to work directly with the first view’s layer).Ĭame = CGRectMake(0, 0, 640, 300) Let’s see the scene created by the function A_singlePlan. Each function creates a different 3D scene. I have listed 6 functions prefixed with A,B,C,D,E, or F. Open the file TB_3DIntro->viewController.m. Now that you have a basic idea of what a matrix does and how a 3D space is organised let’s do some 3D stuff using Core Animation. So if you want to know more about matrices I suggest you to take a look at this article.

Personally, I feel more confident with my code if I know how it works in the background (the basics of it, at least). Core Animation does it for you in a totally opaque way. If you need to perform other transformations, like rotation or translation, you’ll have to set the matrix with a different scheme.įear not, you don’t need to know more than that and you are not supposed to do this operation directly. To be precise the previous matrix is used to perform the scale operation, where X, Y and Z represent the scale values that you want to apply for each axis. Multiplying this matrix by the coordinate of each point of an object (in 3D they are also called vertices), we obtain a transformation of the original object.

You can think of a matrix as a grid of values in some ways similar to a multi dimensional array.įor example, in 3D spaces we use a 4X4 Matrix like this: Using matrices is the right way to implement these operations. Performing transformations like translation, scale and rotation to an object in a 2D or 3D space needs some math calculations.

In that space we can move an object vertically, horizontally and by depth simply by changing its X,Y,Z coordinates. 3D and Matrices (a bit of math… but just a bit!)ĭrawing into a 3D space means adding depth to the standard X and Y 2D space we are used to in iOS. If you want to create your own project remember to add the QuartzCore framework to it.
