PointXYZRGB (uint8_t _r, uint8_t _g, uint8_t _b) |
A point structure representing Euclidean xyz coordinates, and the RGB color.
Due to historical reasons (PCL was first developed as a ROS package), the RGB information is packed into an integer and casted to a float. This is something we wish to remove in the near future, but in the meantime, the following code snippet should help you pack and unpack RGB colors in your PointXYZRGB structure:
// pack r/g/b into rgb uint8_t r = 255, g = 0, b = 0; // Example: Red color uint32_t rgb = ((uint32_t)r << 16 | (uint32_t)g << 8 | (uint32_t)b); p.rgb = *reinterpret_cast<float*>(&rgb);
To unpack the data into separate values, use:
PointXYZRGB p; // unpack rgb into r/g/b uint32_t rgb = *reinterpret_cast<int*>(&p.rgb); uint8_t r = (rgb >> 16) & 0x0000ff; uint8_t g = (rgb >> 8) & 0x0000ff; uint8_t b = (rgb) & 0x0000ff;
Alternatively, from 1.1.0 onwards, you can use p.r, p.g, and p.b directly.
