This is a list of all pdp objects and abstractions with a minimal description. Take a look at the patches in the doc/ directory for more info. (Messy doc & test patches can be found in the test/ directory.) general purpose pdp modules: pdp_del a packet delay line pdp_reg a packet register pdp_snap takes a snapshot of a packet stream pdp_trigger similar to pd's trigger object pdp_route routes a packet to a specific outlet pdp_loop a packet loop sampler (packet array) pdp_description output a symbol describing the packet type pdp_convert convert between packet types image inputs/outputs: pdp_xv displays images using the xvideo extension pdp_glx displays images using opengl pdp_v4l reads images from a video4linux device pdp_qt reads quicktime movies image processors: pdp_abs absolute value pdp_add adds two images pdp_and bitwize and pdp_bitdepth set bit depth pdp_bitmask apply a bit mask pdp_bq spatial biquad filter pdp_bqt temporal biquad filter pdp_cog gaussian blob estimator pdp_constant fills an image with a constant pdp_conv horizontal/vertical seperable convolution filter pdp_cheby chebyshev color shaper pdp_chrot rotates the chroma components pdp_flip_lr flip left <-> right pdp_flip_tb flip top <-> bottom pdp_grey converts an image to greyscale pdp_grey2mask converts a greyscale image to an image mask pdp_hthresh hard thresholding pdp_mul multiplies two images pdp_mix crossfade between 2 images pdp_mix2 mixes 2 images after applying a gain to each of them pdp_noise a noise generator pdp_not bitwize not pdp_or bitwize or pdp_plasma plasma generator pdp_pointcloud convert an image to a point cloud pdp_positive sign function that creates a bitmask pdp_randmix crossfades 2 images by taking random pixels pdp_rotate tiled rotate pdp_scale rescale an image pdp_sign sign function pdp_sthresh soft thresholding pdp_zoom tiled zoom pdp_zrot tiled zoom + rotate pdp_zthresh zero threshold (x<0 -> 0) pdp_xor bitwize xor dsp objects pdp_scope~ a very simple oscilloscope pdp_scan~ phase input scanned synthesis oscillator pdp_scanxy~ x,y coordinate input scanned synthesis oscillator utility abstractions pdp_pps computes the packet rate in packets/sec image abstractions pdp_agc automatic gain control (intensity maximizer) pdp_blur blurs an image pdp_blur_hor horizontal blur pdp_blur_ver vertical blur pdp_contrast contrast enhancement pdp_dither a dither effect pdp_phase applies an allpass filter to an image pdp_phase_hor horizontal allpass pdp_phase_ver vertical allpass pdp_motion_blur blurs motion pdp_motion_phase phase shifts motion pdp_offset add an offset to an image pdp_alledge an all edge detector pdp_conv_emboss emboss pdp_conv_sobel_hor horizontal sobel edge detector pdp_conv_sobel_ver vertical sobel edge detector pdp_conv_sobel_edge sum of squares of hor and ver pdp_saturation change colour saturation pdp_sub subtract 2 images pdp_invert inverse video pdp_gain3 set 3 channel gains independently pdp_gradient converts a greyscale to colour using a colour gradient pdp_png_to convert a png file (on disk) to a certain packet type pdp_tag tag a packet (to use it with route) matrix processors pdp_m_mv matrix vector multiply pdp_m_mm matrix matrix multiply pdp_m_+=mm matrix matrix multiply add pdp_m_LU compute LU decomposition pdp_m_LU_inverse compute matrix inverse from LU decomp pdp_m_LU_solve solve a linear system using LU decomp matrix abstractions pdp_m_inverse compute matrix inverse SEPARATE LIBRARIES: cellular automata (pdp_scaf) pdp_ca computes a cellular automaton (as a generator or a filter) pdp_ca2image convert a CA packet to a greyscale image (obsolete: use pdp_convert) pdp_image2ca convert an image to a CA packet (black and white) (obsolete: use pdp_convert) 3d drawing objects (pdp_opengl) 3dp_windowcontext a drawable window 3dp_draw draw objects (cube, sphere, ...) 3dp_view viewing transforms (rotate, translate, ...) 3dp_light light source 3dp_push push a matrix (modelview, texture, ...) 3dp_dlist compile a display list 3dp_snap copies the drawing buffer to a texture packet 3dp_mode set the current matrix mode 3dp_toggle set some opengl state variables 3d drawing abstractions (pdp_opengl) 3dp_mouserotate connect to 3dp_windowcontext to rotate the scene 3dp_blend turn on accumulative blending mode
