Module sse2

SSE2 Accelerated noise functions.

Use is_x86_feature_detected!("sse2") provided by the Rust stanard library to detect at runtime.

When using the get_ functions, you will get a performance boost when width is evenly divisble by 4, and when it is not small relative height and depth.

Functions

cellular_2d^⚠sse2

Get a single value of 2d cellular/voroni noise

cellular_3d^⚠sse2

Get a single value of 3d cellular/voroni noise

fbm_1d^⚠sse2

Get a single value of 1d fractal brownian motion.

fbm_2d^⚠sse2

Get a single value of 2d fractal brownian motion.

fbm_3d^⚠sse2

Get a single value of 3d fractal brownian motion.

fbm_4d^⚠sse2

Get a single value of 4d fractal brownian motion.

get_1d_noise^⚠sse2

Gets a width sized block of 1d noise, unscaled. start_x can be used to provide an offset in the coordinates. Results are unscaled, ‘min’ and ‘max’ noise values are returned so you can scale and transform the noise as you see fit in a single pass.

get_1d_scaled_noise^⚠sse2

Gets a width sized block of scaled 2d noise start_x can be used to provide an offset in the coordinates. scaled_min and scaled_max specify the range you want the noise scaled to.

get_2d_noise^⚠sse2

Gets a width X height sized block of 2d noise, unscaled. start_x and start_y can be used to provide an offset in the coordinates. Results are unscaled, ‘min’ and ‘max’ noise values are returned so you can scale and transform the noise as you see fit in a single pass.

get_2d_scaled_noise^⚠sse2

Gets a width X height sized block of scaled 2d noise start_x and start_y can be used to provide an offset in the coordinates. scaled_min and scaled_max specify the range you want the noise scaled to.

get_3d_noise^⚠sse2

Gets a width X height X depth sized block of 3d noise, unscaled, start_x,start_y and start_z can be used to provide an offset in the coordinates. Results are unscaled, ‘min’ and ‘max’ noise values are returned so you can scale and transform the noise as you see fit in a single pass.

get_3d_scaled_noise^⚠sse2

Gets a width X height X depth sized block of scaled 3d noise start_x, start_y and start_z can be used to provide an offset in the coordinates. scaled_min and scaled_max specify the range you want the noise scaled to.

get_4d_noise^⚠sse2

Gets a width X height X depth x time sized block of 4d noise, unscaled, start_* can be used to provide an offset in the coordinates. Results are unscaled, ‘min’ and ‘max’ noise values are returned so you can scale and transform the noise as you see fit in a single pass.

get_4d_scaled_noise^⚠sse2

Gets a width X height X depth X time sized block of scaled 4d noise start_* can be used to provide an offset in the coordinates. scaled_min and scaled_max specify the range you want the noise scaled to.
