c# - OpenGL draw every n vertex -


i working on writing application contains line plots of large datasets.

my current strategy load data each channel 1d vertex buffers.

i use vertex shader when drawing assemble buffers vertices (so can reuse 1 of buffers multiple sets of data)

this working pretty well, , can draw few hundred million data-points, without slowing down much.

to stretch things bit further reduce number of points drawn, though simple reduction (i.e. draw every n points) there not point plotting 1000 points represented single pixel)

one way can think of doing use geometry shader , emit every n points not sure if best plan of attack.

would recommended way of doing this?

you can simpler adjusting stride of vertex attributes n times normal one.

sequelize.js - Sequelize: sort by enum cases -

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
