heatmap - Convolve a sector along a trajectory to make a heat map in python -

-

i have built vr arena fly. inside vr world, fly flies has objects in it. vr world built using panda 3d game engine. record trajectory of fly. obtain position (x,y) , heading (theta) function of time.

briefly, trying is, heatmap of fly saw flew. heatmap representation of world intensities corresponding how visible fly. more fly stared @ particular place flying towards it, hotter regions get. trajectory plot explains path if fly point. doesn't convey fly saw flew. fly sees virtual world based on vr camera parameters. has field of view (fov), max draw distance , orientation (heading). traverses through world, sees sector (pie shaped wedge) of entire world.

what want implement method keep count of how many frames each point on map came inside camera's fov (the sector).

this naively results in sector traversing along trajectory , incrementing counter @ points inside sector. after entire traversal, need plot matrix heatmap. think fair representation of fly saw in it's trajectory.

conceptually, task doable multiple loops. not sure how go implementing vectorized form can happen in lifetime. using python

i have postgresql db number of tables. if query: select column_name information_schema.columns table_name="my_table"; i list of columns returned properly. however, when query: select * "my_table"; i error: (programmingerror) relation "my_table" not exist 'select *\n "my_table"\n' {} any thoughts on why can columns, can't query table? goal able query table. you have include schema if isnt public one select * <schema>."my_table" or can change default schema show search_path; set search_path my_schema; check table schema here select * information_schema.columns for example if table on default schema public both works ok select * parroquias_region select * public.parroquias_region but sectors need specify schema select * map_update.sectores_point

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
