Irrlicht Engine

sorry, i forget to static linking for the the gcc and cpp (-static-libgcc -static-libstdc++). updated, it should works now.

i feel like an airplane pirate

The ray already move inside local space, not in the world space. Distance value are not a concern, in ray marcing, the ray can easily skip huge empty gap, due to the nature of distance functions (i use inigo quiles distance function). What i think people are not aware of, is that the ray can actuall...

what are you ray-marching? Basically cube, just imagine there are terrain inside a cube. Ray march moving againts the cube which constantly changing its height. Some other objects are sphere and cylinder, the same idea goes, a sphere that constantly change its radius. When the expected distance err...

thanks Vectrotek. the rendering thingy supposed to be release along with my jungle scene node, for rendering the trees, volumetric tree bark, ivy, leaves dll . at this stage, it just barely works, code are not elegant, far from readable :oops: , i think a lot of people will spot stupid hacks going o...

ray marching in irrlicht vanilla 1.8.4. every are thing drawn inside fragment shader. deferred rendering done to calculate lighting, shadow and stuff. i this project stuck, too hard to get good framerate.

actually i write this code for testing the texture->lock() testing. but i think everybody can use it too. so here it is the matrix2D. the first thing we need for drawing 2d graphic is a good transformation tool. the matrix2D class has the complete 2D operation needed to transform vertices in 2d mann...

here is the file http://s000.tinyupload.com/index.php?fi ... 1091381843
i hope it is sufficient for the case.

hai CuteAlien. thanks for the reply. yes the texture creation flag solve my problem. about the simple test. do you still need it? how do you want it? is codeblock project ok?

i am trying to implement marching cube to create polygon shapes out of ITexture for 2D physic game. the process requires pixel access. here is the code i use for getting the texels.   core::dimension2d<u32> dimension = texture->getOriginalSize(); u8 * texels = (u8 *)texture->lock(video::ETLM_READ_ON...

thanks again hendu. actually pretty obvious isn't it. i was hopping for "a hidden trick" . thanks again.

There's a blog post by Unity that explains how to do float packing in shaders. Try to look it up, can't remember what the title was. IIRC it was by Aras P, like most useful things there. thanks hendu. i found that article. an also i found this ECF_G32R32F you mention earlier, strange cant find it b...

correct me if i'm wrong. i think i know how to use several vector components to store single value. and it doesn't involve bitwise. for example i can store it as below right?

thank you guys. i have a big plan on these trees. volumetric ivy, cracks, leaves, etc are coming hopefully next release if i could, i'm working on my ray marching for richer geometry detail. probabbly not even close to a good article, but here's my progress https://kornwaretm.wordpress.com/2016/08/2...
