I'm working with SFML right now, and upon finishing the tutorials I still do not know how to give a shape a texture or image -- not just a solid color/outline. The only thing I know can take an image is a sprite, but thats way to simple, as it only allows you to render rectangular images in a rectangluar way! What are the techniques for rendering images onto shapes, and only inside the shape? It would be great if some of you could provide some resources or SFML-specific stuff! |

I don't think you can do this directly using SFML. It looks like the shape class will not support texture mapping; allegedly it is a planned feature for the next version (discussion). Depending on the kind of visual effect you are going for -- I didn't find your description entirely clear -- you could do something like using a shape to mask a sprite, as described in this post (scroll down a ways, there's an image with the example result), or you could use OpenGL directly to render a series of texture-mapped triangles with the image mapped appropriately using texture coordinates. Note that while sprites are rectangular in their nature, you can achieve the visual result of a non-rectangular image by including transparency (typically via the alpha channel of the image), and that may be all you need to achieve your desired visual result. |
