Hi,
I would like to start with pdp and pidip. Is there any manual or list objects?
Documentation is scarce, almost non-existent in fact besides the sometimes-helpful helpfiles that come with the objects. Here's a list, which I've included in the FLOSS Manual for PD that I'm working on.
Good luck! d.

PDP
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

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
