Semi-transparent triangles & circles over a colourful background. Works nicely on my Android phone (Motorola Moto G4).

Same program as previous, but now with an FPS indicator.

I get 32 fps (average) on my Moto G4, which isn't bad considering that all the graphics is software-rendered (no hardware acceleration) on a relatively slow processor. More efficient colour-blending code (for both x86 and ARM architectures) ought to at least double the speed of the rendering.

Rotating blue flowers (x86 & ARM bitmap rotation test):

Tested under BB4W, BBCSDL Win32, BBCSDL Android (ARM).

Continuing my development of a little software graphics library for a possible Android game project, here's a flood fill demo (the 'flower' shape is flood-filled in real-time). Very sub-optimal (especially for ARM processors), but fast enough for my needs.

The following YouTube video is a summary of my experiments with BBCSDL on an ARM-based Android device. Something seems to be messing up the colour gradients (possibly with the video capture software which I downloaded minutes before making the video!). There is some inevitable 'colour banding' due to the reduced colour bit depth imposed by SDL (16bpp as opposed to the usual 24- or 32bpp), but something went very wrong and the colour banding/quantization problem isn't actually as bad as what is portrayed in the video.
