Hi all, I don't seem to be able to get my translated matrix working, although the same technique works fine with scale and rotate.

To extend the feature set supported by GLM and keeping the library as close to GLSL as possible, new features are implemented as extensions that can be included thought a separated header:.

We may prefer to use the approaches describe in the two following sections to keep the project build fast. Hence, user projects could only include the features they actually use. Following is the list of all the core features, based on GLSL specification, headers:. GLM packages a glmConfig. GLSL supports implicit conversions of vector and matrix types.

For example, an ivec4 can be implicitly converted into vec4. Often, this behaviour is not desirable but following the spirit of the library, this is the default behavior in GLM. However, GLM 0. In order to satisfy alignment requirements of all non-static members of a class, padding may be inserted after some of its members. GLM supports both packed and aligned types. Packed types allow filling data structure without inserting extra padding. To use the default precision functionality, GLM provides some defines that need to added before any include of glm.

Some platforms Dreamcast doesn't support double precision floating point values. To compile on such platforms, GCC has the --m4-single-only build argument. Effectivement, all the float64 types are no longer defined and double behaves like float. Shader languages like GLSL often feature so-called swizzle expressions, which may be used to freely select and arrange a vector's components. For example, variable. Swizzle expressions can be written with characters from exactly one of xyzw usually for positionsrgba usually for colorsand stpq usually for texture coordinates.

GLM supports some of this functionality.

Note: Enabling swizzle expressions will massively increase the size of your binaries and the time it takes to compile them! Swizzle operators return a copy of the component values, and thus can't be used as L-values to change a vector's values. This permits a powerful swizzling implementation that both allows L-value swizzle expressions and GLSL-like syntax.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have a mat4 called model. I want my cube to orbit around a position. I am able to call the glm::rotate mat4, angle, vec3 just fine and have it rotate at its origin.

Unfortunately my cube is frozen in place when I add the glm::translate call after the rotation.

Is there something basic I'm missing? Otherwise you are resetting and translating the Identity matrix, which will completely overwrite your rotation. Learn more. Asked 1 year, 7 months ago. Active 1 year, 7 months ago.

Game Development Stack Exchange is a question and answer site for professional and independent game developers. It only takes a minute to sign up. The aim of my program is to render a simple colored triangle in rotation. The rotations are correct if all Z values of my vertices are equals to 0. If one of these values are different of 0.

So if the polygon is coplanar with the plane x0y it's ok, but in the other case it's not correct. I searched to find the problem in my matrix usage in vain. Here's a part of my code :. I tried several combinations of code without any success.

I'm lost. Does anyone can help me, please? But for anybody wondering why, I'll try to explain it. When you call glm::translateglm::rotateor glm::scale the first parameter you pass in is the matrix to perform the transformation on. So when the first example calls glm::rotatefor example, it takes the model variable, which is passed in as a parameter, rotates it and then returns the new rotated matrix.

Until then, we only considered 3D vertices as a x,y,z triplet. We will now have x,y,z,w vectors. What difference does this make? When you rotate a point or a direction, you get the same result. However, for a translation when you move the point in a certain directionthings are different. Not much.

Homogeneous coordinates allow us to use a single mathematical formula to deal with these two cases. Simply put, a matrix is an array of numbers with a predefined number of rows and colums. For instance, a 2x3 matrix can look like this :. In 3D graphics we will mostly use 4x4 matrices. They will allow us to transform our x,y,z,w vertices.

This is done by multiplying the vertex with the matrix :. Put your left finger on the a, and your right finger on the x. This is ax. Move your left finger to the next number band your right finger to the next number y. Once again : cz. Once again : dw. These are the most simple tranformation matrices to understand.

A translation matrix look like this :. Remember, the 1 means that it is a position, not a direction. Well, in fact, you almost never do this in GLSL. This one is special. These are quite complicated. For more information, please have a look to the Matrices and Quaternions FAQ popular resource, probably available in your language as well.

You can also have a look at the Rotations tutorials. So now we know how to rotate, translate, and scale our vectors.

It would be great to combine these transformations. This is done by multiplying the matrices together, for instance :. This is how matrix multiplication works. As a matter of fact, the order above is what you will usually need for game characters and other items : Scale it first if needed; then set its direction, then translate it. For instance, given a ship model rotations have been removed for simplification :. The Model, View and Projection matrices are a handy tool to separate transformations cleanly.

But you should. This model, just as our beloved red triangle, is defined by a set of vertices. Your vertices are now in World Space. This is the meaning of the black arrow in the image below : We went from Model Space all vertices defined relatively to the center of the model to World Space all vertices defined relatively to the center of the world. When you think about it, the same applies to cameras.
