thanx

Hm... I tried deleteAllKeyframes but it also disconnects parms from selectors in sops

Good offer

Yes. Why? Maybe because it doesn`t selecting when you clicking - it is only for dragging

I can find primitive under the mouse with MouseCHOP. Now i wat to find closest point at this primitive. The problem is that nearpoint expression function return near point to viewport plane. As the result I can find valid point number in flat grid and via one of ortho views. How to properly find closest point ? I have to consider direction (in my code) returned by mapToWorld. But How ? import hou, toolutils cur_viewport = toolutils.sceneViewer().curViewport() # CURRENT VIEWPORT mx, my = hou.evalParmTuple("/obj/geo1/dm1/core/mouse") # THIS IS PATH TO MOUSE-CHOP vx, vy = v.mapFromMouseChop(mx,my) # GET VIEWPORT COORDINATES direction, position =v.mapToWorld(vx,vy) # CONVERT VIEWPORT TO WORLD COORDINATES node = cur_viewport.queryNodeAtPixel(vx, vy) # NODE AT WORLD COORDINATES if node is not None: prim = v.queryPrimAtPixel( node, vx, vy ) # PRIM AT WORLD COORDINATES hou.hscriptExpression( 'nearpoint("{}",{},{},{})'.format(node.path(), position[0], position[1], position[2]) ) # POINT NUMBER

Thanx, i`ll try it

Dmitry Shurov look at this simple example:http://youtu.be/L7i0AaezN-4

When your tool is active, you can temporary create CHOP subnet with MouseCHOP inside and work with mapFromMouseChop. Also you can hide subnet node when tool is active.

And you are right. reloading module is a fastest way

what about 5-10 lines of python expression. i need to create file with module for this?

Not so difficult. for me it is: 1. focus code field 2. alt+e twice 3. edit code 4. ctrl+w+enter 5. click on accept button in internal editor strages It doesn`t work with sublime 3, but it works with sublime 2

it seems to me that it is impossible with python

No one:) But maya has better class\members description

AND WELL DOCUMENTED HDK

Hscript expressions a bit faster than python expressions. But Python more powerful

Working in one context to modify geometry, like animation with expressions, VEX, etc in SOP context. Just modify geometry shape with time in one place (all nodes on a look). For this purpose it isn't obligatory to move dynamic operations to separate container, especially for not very large sims.

Tweak-like state with preselection highlighting of components would be good. eXSI users i think you need it

I have 2 HDK questions: 1. how to get primitive\vertex\point\edge under the mouse pointer? 2. how to highlight this component with opengl? I can only get primitive under the pointer with hou.GeometryViewport.queryPrimAtPixel and hou.GeometryViewport.mapFromMouseChop. But i need hdk solutions. There are very low info for this . I see DM_VPortAgent.singlePickObject method, but i dont understand how to work with render hooks

THANK YOU VERY MUSH !!! IT WORKS !!!

What kind of optimisations we need to modeling like this ? I think we simply need custom state(s) in Houdini. IMO the speed of viewport is good for this kind of operations.

Whether someone can build MSS_CustomBrushState HDK example in Linux ? I tried gcc-4.8.2 and gcc-4.6.4. All examples builds normally and work, except several custom state examples. I so much need to deal with it Thanx...

Help me please http://youtu.be/fMBiz-APzHQ What im doing wrong ?

Flatten sop example works well

After i seted it error with ui file was gone

At now id dont think that it is problem with ui file but it also crash with this log: Crash report from alexey; Houdini FX Version 13.0.338 [linux-x86_64-gcc4.6] Traceback from Sun Mar 2 20:10:43 2014 Caught signal 11 AP_Interface::coreDumpChaser(UTsignalHandlerArg) <libHoudiniUI.so> AP_Interface::si_CrashHandler::chaser(UTsignalHandlerArg) <libHoudiniUI.so> signalCallback(UTsignalHandlerArg) <libHoudiniUT.so> UT_Signal::UT_ComboSignalHandler::operator()(int, siginfo*, void*) const <libHoudiniUT.so> UT_Signal::processSignal(int, siginfo*, void*) <libHoudiniUT.so> killpg <libc.so.6> PI_ResourceManager::getBindingSelectors(OP_Operator*) const <libHoudiniPRM.so> MSS_SingleOpState::findNextParmWithSelector(int) const <libHoudiniAPPS3.so> MSS_SingleOpState::handleSelectorDone(UI_Event*) <libHoudiniAPPS3.so> BM_SingleOpState::generate(BM_SimpleState::BM_EntryType, bool) <libHoudiniAPPS2.so> MSS_SingleOpState::generate(BM_SimpleState::BM_EntryType, bool) <libHoudiniAPPS3.so> BM_OpStateControl::enterState(BM_State*, BM_OpStateEntry) <libHoudiniAPPS2.so> BM_OpStateControl::setCurrentState(char const*, int, BM_OpStateEntry, BM_SceneManager*) <libHoudiniAPPS2.so> HOMF_SceneViewer::setCurrentState(char const*, bool) <libHoudiniAPPS3.so> _wrap_SceneViewer_setCurrentState <_hou.so> PyEval_EvalFrameEx <libpython2.7.so.1.0> PyEval_EvalCodeEx <libpython2.7.so.1.0> PyEval_EvalFrameEx <libpython2.7.so.1.0> PyEval_EvalCodeEx <libpython2.7.so.1.0> PyEval_EvalCode <libpython2.7.so.1.0> PY_CompiledCode::evaluateUsingDicts(PY_Result::Type, void*, void*, PY_Result&) const <libHoudiniUT.so> SHLF_Tool::execute(SHLF_ExecContext const&) <libHoudiniAPPS2.so> OPUI_ToolHandler::handleToolEvent(UI_Event*) <libHoudiniAPPS2.so> UI_Queue::processNextEvent() <libHoudiniUI.so> UI_Queue::drain() <libHoudiniUI.so> UI_Queue::eventLoop() <libHoudiniUI.so> main <libHoudiniUI.so> __libc_start_main <libc.so.6> [0x1bd7] <houdinifx-bin>
